@rastriginsfcn

are there any other besides rastriginsfcn?

Best Answer

You can use any objective function from Optimization Toolbox or Global Optimization Toolbox. In particular,

expensive_objfun
objfun
onehump
ackleyfcn
cantileverVolume
dejong1fcn
dejong2fcn
dejong5fcn
lincontest2
lincontest6
lincontest7
ps_example
simple_fitness
simple_objective

Take a look at the featured examples for these and more.

MATLAB: Is there a documentation error in the “Example::Minimizing De Jong’s Fifth Function.” in Genetic Algorithm and Direct Search Toolbox 2.1 (R2007a)

This is an error within the documentation for Genetic Algorithm and Direct Search Toolbox 2.1 (R2007a). The documentation should implement the correct syntax as follows:

fun = @dejong5fcn;
[x fval] = simulannealbnd(fun, [0 0])

MATLAB: Specifying constraints for optimization using GA

As documented, when using a custom population type, "ga ignores all constraints, including bounds, linear constraints, and nonlinear constraints." So your custom creation, crossover, and mutation functions must enforce your constraints.
