According to Wikipedia, the all-sure source of knowledge: Mutation Mutation affects an individual in the population. It can replace a whole node in the selected individual, or it can replace just the node's information. To maintain integrity, operations must be fail-safe or the type of information the node holds must be taken into account. For example, mutation must be aware of binary operation nodes, or the operator must be able to handle missing values. Therefore, and many will want to slap me for this, there cannot be maintainance of integrity required without Anyway, I just wanted to clarify that because Gibberstein brought it up in the pretty dead Three Issues thread.

GP is a pragmatic field more interested in usable techniques than strict modelling, so they will use methods that improve efficiency, even if they aren't perfect mirrors of living genetics. However, it's not a big difference - the randomisation may be constrained by the syntax, but it is still random - the mutation process has no idea at all about the goal of the overall process. If you want it to be more representative, you can remove the syntax constraints and the overall process will still work, but less efficiently - you'll have a lot more programs that are (by biological analogy) stillborn. -- "lets say Portal is a puzzle game, so its a rehash of Tetris" |

If you're too draw from Wikipedia to suggest "Genetic programming is barely related to true evolution," I suggest not having the linked page use evolution/evolutionary eight times in the course of the page's information; merely sets a bad tone.
Biological evolution has no mechanism beyond the attempted organism itself to determine if a mutation is deleterious, deleterious to the extent of being fatal, neutral, or advantageous. Deleterious mutations, being those which affect the ability of the organism to produce viable offspring, either do not get passed on due to death of the mutation via death of the (potential) organism or become passed on less than advantageous mutations. This would be the fail-safe which you absolutely neglected which lead you to say, "there cannot...without," despite having quoted two possibilities just prior. Genetic programming is still quite related to biological evolution by using the Mutation/Heredity/Natural Selection scheme, even if it is goal-oriented with controlling observers for efficiency concerns. However, Gibberstein noted in the previous thread genetic programming's use of this Mutation/Heredity/Natural Selection scheme as a counter to your errant, frequent use of code to show that only degeneration is possible. |

I don't think he meant evolution by means of mutation is impossible; just very improbable. Also what thread are you all speaking from? Edited by: NGS616 |

You do get what kind of timescale we're looking at for biological evolution? There's been countless millenia to allow for trillions of failures. To see something similar happening in a human observable timeframe naturally requires a few constraints to focus the process. None of which changes the original reason I mentioned it - you stated that a random process would always lead to degeneration, and used program code as your example. This is a random process operating on program code, and it proves your degeneration statement wrong. -- "lets say Portal is a puzzle game, so its a rehash of Tetris" |

Although I can critique in more detail when I have more time, I can sum it up pretty quickly. Basically he's moaning that the process has been optimised so it's a practical problem-solving technique, rather than a direct model of the biological process. Most if not all of his points can be adddressed at the expense of efficiency if your goal is modelling the biological process rather than solving a specific problem as quickly as possible. -- "lets say Portal is a puzzle game, so its a rehash of Tetris" |

Merely to imply once more, genetic programming was not designed to simulate biological evolution but to use the Mutation/Heredity/Natural Selection scheme of evolution; he acknowledges this, "GAs use mathematical constructs that parallel mutations..., natural selection..., and even some type of ‘recombination’..." (ellipsis replace statements in parenthesis to clarify). Despite a myriad of artificial restraints, interactions, etc., he doesn't demonstrate that "GAs do not mimic or simulate biological evolution," but that they are not exactly analogous to the process. One would think this should be obvious considering genetic programming is used to develop software.
No, your point appears to be to, again, piss out whatever disinformation possible whilst ignoring discussion to the contrary to maintain feeling intelligent and special regarding your lack of study. This is why you link to an article with the same faulty premises as your beginning to this topic. |

Lets nail this one straight away. The first person to use computer code as an analogy for arguing their case was you. I merely cited a relevant counter example.
This sounds like a deliberate and dishonest attempt to confuse the framework with the process. GA/GP requires outside intelligence to build the framework, but once that is built the GA/GP process is not directed by outside intelligence at all. A smart engineer can tweak things to improve the time it takes to find a good solution, but the technique is robust and general-purpose enough to cope without such tweaks, it just takes longer.
Nothing is perfect, and there are disreputable people out there. This is an unfortunate fact of life, and totally irrelevant to the issue being discussed in this thread. If you can't find fault with the facts that are on-topic, I can only assume that you are trying to confuse matters to hide the fact that you have nothing relevant to say. -- "lets say Portal is a puzzle game, so its a rehash of Tetris" |

The issue has been covered by both myself and Gibberstein (Gibberstein has now covered this a second time in reply to this more recent comment). You are currently arguing against the relevancy of your own comments in the previous thread.
I merely wanted to quote the sentence to assure you do not change anything because this well highlights the recycled rhetoric Creationists engage in; you claim a biased perspective as the rationale behind the comparison of genetic programming and evolutionary theory when, as explained, genetic programming uses the primary mechanisms of evolutionary theory because you've no other way to seemingly dispel the demonstrative powers of the mechanisms except to claim bias.
Code is not a natural occurring reproductive system. However, as explained genetic programming and evolution are not "completely different", and this is because "genetic programming uses the primary mechanisms of evolutionary theory," but it "is a pragmatic field more interested in usable techniques than strict modelling" - Gibberstein.
No, you don't care. Notice how we are still correcting your repetitious, false assertions.
Already discussed this previously. However, since we've played at your game for a few comments, how about answering some questions for me related to your example? What do you believe is fraudulent in Haeckel's drawings? Do you believe there is no merit in showing Haeckel's drawings? What fraud have Creationists exposed within any scientific field? What fraud have Creationists exposed to their own detriment? |

We're dancing around definitions here. One thing that would be extremely useful to clean up is that there is a difference between Genetic Algorithms and Genetic Programming. They share some commonality, as GP is an extension of GA, but it would be wrong to assume that all the limitations of GA apply to GP. Also 'completely original' is open to a lot of flexibility in interpretation, so I'll state exactly what GP is capable of. It starts with totally random orderings of base programming constructs (if branching, mathematical operators, that kind of thing. Nothing specific to any problem) and through a process that has no awareness of how to fulfil the goal, only how to assess the suitability of a solution, produces a program that correctly solves a complex problem. It's dangerous to bring a subjective measure into something where I want to avoid ambiguity, but to offer a crude but easily understood guide as to what this means, it's taking something with the functionality comparable to an amoeba up to a complexity comparable to the nervous system of an insect. Please accept that this a broad metaphor measuring against something intuitive rather than a literal comparison of functionality though. Edited by: Gibberstein |

Do you earnestly believe you came near answering even one of the four questions I asked?
Because evolution has non-technical definitions, whereas what we are speaking is biological evolution referring to allele frequencies in populations changing over time due to descent with modification via genetic mutation and selection of fitness of traits.
...is wrong because "transportation" cannot reproduce.
Please indicate where I or Gibberstein have made such a reference. If you are unable, please stop constructing straw men; not only is this insulting but you are, as per usual, attempting to obfuscating the short-comings of your argument with fallacy.
Weren't you attempting to show the inability for evolution to create novel genetic traits despite the examples you gave possessing the same short-comings which genetic programming does which you are now subtly, and without noting the fact that you were initially incorrect, acknowledging despite having previously lambasted it for not being a strict parallel of biological evolution?
You ignored my previous requests in the "Three Issues" thread for you to define information, despite your having commented on the nebulousness of the term which I remarked by saying, "Information is difficult to define, true." You appear to have used, immediately thereafter, a rather succinct definition (despite previously stating its difficulty) by saying, "We have no demonstration, however, of random garbage noise creating an identifiably coded pattern. That is what I meant." Do you still accept this as a definition? I am doubtful as the definition is rather lackadaisacal and previously answered.
Do not exaggerate the century we've known of DNA, the half century we've known of DNA's role in heredity, the few decades we've been capable of analyzing DNA, or the half decade since we mapped our own genome. However, I've given examples of novel genetics, novel traits, novel advantageous traits, and more. We have observed exactly what is necessary for descent with modification. Now, I and Gibberstein have both performed another bout on your tiring little shotgun rants, so I will repost my previous questions. Please, actually attempt to answer them, all four and in your own words. Otherwise, consider this the last attention I grant you, "What do you believe is fraudulent in Haeckel's drawings? Do you believe there is no merit in showing Haeckel's drawings? What fraud have Creationists exposed within any scientific field? What fraud have Creationists exposed to their own detriment?" |

You know what amazes me about this thread... It amazes me that Robert keeps coming back to try to convince people instead of just accepting that there are people here that believe genetic evolution exists ... and that people continue to respond to him :o ... |

It's nothing to do with existence. It's my stubborn sticking to certain definitions which conflict with most other people's. He who controls definitions, controls the truth. For instance, I am unsure of the benefit of talking about 'fraud' when Vangor has not clarified what 'fraud' actually is. Are peppered moths technically 'fraud'? Are the plethora of ape-men 'fraud'? Is teaching as truth that dinosaurs evolved from birds when there is no evidence, but pretending there is, 'fraud'? Is falsifying embyro diagrams to convince people that unborn children aren't actually human 'fraud'? Who knows, because we don't even agree on a common definition of what 'evolution' is. |

For a few posts there I was genuinely interested in what you guys were talking about. Then I scrolled down, saw the video, read Robert's post above it and gave up. Almost held my attention, but that post single-handedly made me give up on the debate. :\ |
