Questions tagged [genetic-programming]

Genetic programming (GP) is a specialization of evolutionary computation where each individual is a computer program. It is used to optimize a population of computer programs according to a fitness landscape determined by a program's ability to perform a given computational task.

Genetic programming (GP) is a type of where each individual in a population is a computer program. It is used to optimize a population of computer programs according to a fitness landscape determined by a program's ability to perform a given computational task.

Traditional genetic programming, originally popularized by John Koza, represents code as expression trees, but this topic also includes other systems in which code evolves.

See also: , which refers to evolution-inspired algorithms in which an abstract representation of the solution is being evolved, rather than code itself.

How to use the best individual in pyevolve genetic programming

I apply GP in pyevolve to train and it gives me the best tree. I would like to use this tree to test different data. I want to keep min is root of the tree, so the function will return -1 if gp_add, gp_mul... is the root of tree. This is example…

Use GP for Solving Symbolic Regression

I understand how to solve a simple symbolic regression problem such as f(x)=x4+x3+x2+x. However, I'm not quite sure how to use GP to solve the below one. f(x) = x2 + cosx + 7, for x<=0, 1/x + 2x, for x>0 Can anyone help with this?
