Evolutionary algorithms (EAs) are inspired by the biological model of evolution and natural selection. In the natural world, evolution helps species adapt to their environments. Evolutionary algorithms are based on a simplified model of this biological evolution. To solve a particular problem we create an environment in which potential solutions can evolve.

Evolutionary algorithms (EAs) are inspired by the biological model of evolution and natural selection. In the natural world, evolution helps species adapt to their environments. Evolutionary algorithms are based on a simplified model of this biological evolution. To solve a particular problem we create an environment in which potential solutions can evolve. The environment is shaped by the parameters of the problem and encourages the evolution of good solutions.

The field of Evolutionary Computation encompasses several types of evolutionary algorithm. These include Genetic Algorithms (GAs), Evolution Strategies, Genetic Programming (GP), Evolutionary Programming and Learning Classifier Systems.

What are good examples of genetic algorithms/genetic programming solutions?

Genetic algorithms (GA) and genetic programming (GP) are interesting areas of research. I'd like to know about specific problems you have solved using GA/GP and what libraries/frameworks you used if you didn't roll your own. Questions: What…

What is the difference between genetic and evolutionary algorithms?

Is there a difference between genetic algorithms and evolutionary algorithms? I have read multiple papers, talking about genetic or evolutionary algorithms, and while very similar, I think they may not be the same thing.

What is holding genetic programming back?

I have done a fair amount of work with genetic algorithms quite successfully and thus far ignored genetic programming. As far as I know, most programs remain written by programmers, and I'm curious to know what is holding genetic programming…

Roulette Selection in Genetic Algorithms

Can anyone provide some pseudo code for a roulette selection function? How would I implement this: I don't really understand how to read this math notation. I never took any probability or statistics.

Machine Learning Algorithm for Predicting Order of Events?

Simple machine learning question. Probably numerous ways to solve this: There is an infinite stream of 4 possible events: 'event_1', 'event_2', 'event_4', 'event_4' The events do not come in in completely random order. We will assume that there are…

Code generation by genetic algorithms

Evolutionary programming seems to be a great way to solve many optimization problems. The idea is very easy and the implementation does not make problems. I was wondering if there is any way to evolutionarily create a program in ruby/python script…

What are the differences between genetic algorithms and evolution strategies?

I've read a couple of introductory sections of books as well as a few papers on both topics, and it looks to me that these two methods are pretty much exactly the same. That said, I haven't had the time to actually deeply research the topics yet, so…

How to utilize Hebbian learning?

I want to upgrade my evolution simulator to use Hebb learning, like this one. I basically want small creatures to be able to learn how to find food. I achieved that with the basic feedforward networks, but I'm stuck at understanding how to do it…

Can any existing Machine Learning structures perfectly emulate recursive functions like the Fibonacci sequence?

To be clear I don't mean, provided the last two numbers in the sequence provide the next one: (2, 3, -> 5) But rather given any index provide the Fibonacci number: (0 -> 1) or (7 -> 21) or (11 -> 144) Adding two numbers is a very simple task for…

Parallel application in python becomes much slower when using mpi rather than multiprocessing module

Lately I've observed a weird effect when I measured performance of my parallel application using the multiprocessing module and mpi4py as communication tools. The application performs evolutionary algorithms on sets of data. Most operations are done…
