Genetic algorithm solves smooth or nonsmooth optimization problems with any types of constraints, including integer constraints. It is a stochastic, population-based algorithm that searches randomly by mutation and crossover among population members What Is the Genetic Algorithm? The genetic algorithm is a method for solving both constrained and unconstrained optimization problems that is based on natural selection, the process that drives biological evolution. The genetic algorithm repeatedly modifies a population of individual solutions GENETIC ALGORITHM MATLAB Genetic Algorithm consists a class of probabilistic optimization algorithms. GENETIC ALGORITHM MATLAB tool is used in computing to find approximate solutions to optimization and search problems. Set of possible solutions are randomly generated to a problem, each as fixed length character string With a large population size, the genetic algorithm searches the solution space more thoroughly, thereby reducing the chance that the algorithm returns a local minimum that is not a global minimum. However, a large population size also causes the algorithm to run more slowly. The default is '50 when numberOfVariables <= 5, else 200'

Genetic algorithms are parameter search procedures based on the mechanics of natural genetics. They combine a Darwinian survival-of-the-fittest strategy with a random yet structured information. The format for writing a genetic algorithm in Matlab is as follows: f_min = ga(@function,nvars,A,B,Aeq,Beq,LB,UB,nonlcon,intcon,options) Explanation of terms involved: f_min is the local minima point. @function is the function to be called. (In our case, its the stalagmite function) nvars indicates the no of variables used. A and B are used to indicate any kind of inequalities that exist in.

Genetic algorithms are used for many things. In this case it's a linear genetic programming problem, where a sequence of four genes encode an instruction. The first gene is an operator, the second a destination register, the third and fourth are operands. I can't split up an instruction, therefore I need the crossover points to lie on 4, 8, 12 etc. I am using randperm to get two unique.

This toolbox provides a modular, extensible, portable algorithm in an environment rich in math- ematical capabilities. The toolbox has been tested on a series of non-linear, non- convex, multi-modal functions. The results of these tests show that the algorithm is capable of nding better solutions with less function evaluations than simulated.
