Hi there diggoran, I got your message asking about Walkinator, I’m glad you enjoyed it!

The key to the AI in Walkinator is simply how many iterations the computer is able to calculate in a relatively short amount of time. Basically it boils down to this: It first runs the simulation in a for loop with a predetermined number of iterations with a random set of instructions for the various muscles, it then scores the instruction set based on how far the creature got, and then generates more random instructions and scores them the same way. Essentially, the whole thing could continue randomly… It would just take a really long time for it to get any good results. This is where mutation/crossover comes in… After a certain number of random generations, it picks the top ones and mutates the instructions just a little bit to get new instructions to test. It also does a crossover operation on some instructions too(basically taking two instruction sets and splicing them together). Also, it has some other little tricks like adding a bit more randomness if it goes for awhile without finding a better solution. I think that sums it up pretty nicely… theres some good articles out there on genetic programming that go into better detail too.

Digg, all input is welcome, but what you have said is compleaty wrong. All my graphics are 100% orignal, nothing was used from the shootorial, secondly how is the game extaclly the same ? indroduction screen, storyline, credits page, 5 different levels, 13 different ships, i would like to know were the shootorial had all that and showed you how do code all that. Anyways Thanks for you input.
