is a versatile optimizer able to outperform both human experts and conventional heuristics in finding the optimal solution of hard problems.
Given a task, it first fosters a set of random
solutions, then iteratively refines and enhance them.
Its heuristic algorithm uses the result of the evaluations, together with
some internal structural information, to efficiently explore the search space,
and eventually to produce the optimal solution. µGP has been devised in
in the CAD Group
at Politecnico di Torino,
and subsequently developed thanks to the effort
µGP original application was the creation
of assembly-language programs
hence the Greek letter µ (micro) in its name.
Afterward, it has been used on a wider range of problems, such as:
creation of test programs
and post-silicon validation
design of bayesian networks
creation of mathematical functions
represented as trees
and combinatorial optimization
real-value parameter optimization
and even creation of corewar warriors
µGP is an
hence the GP acronym (genetic programming) in its name.
A population of different solutions
is considered in each step of the search process, and new individuals
are generated through mechanisms that ape both sexual
. New solutions inherit
distinctive traits from existing ones, and may coalesce
the good characteristics of different
parents. Better solutions have a greater chance to reproduce and to
succeed in the simulated struggle for existence
