Re: Easily Implementation of a Genetic Algorithm Mutation function

I have found a very dumb way to work around my issue:
function MutChrom = mut(OldChrom,Pm)
echo on
% get population size (Nind) and chromosome length (Lind)
[Nind, Lind] = size(OldChrom) ;
% definition of probality for mutation to happen
Pm = 0.7/Lind;
% creation of matrix of random numbers
RandMat=rand(Nind,Lind);
MutChrom=OldChrom;
for n=1:Nind
for m=1:Lind
%check probability
if Pm>=RandMat(n,m)
% perform mutation on chromosome structure
if m==1
MutChrom(n,m)=randi([1,3],1);
elseif m==2
MutChrom(n,m)=randi([4,5],1);
elseif m==3
MutChrom(n,m)=randi([6,8],1);
elseif m==4
MutChrom(n,m)=randi([9,12],1);
elseif m==5
MutChrom(n,m)=randi([13,23],1);
elseif m==6
MutChrom(n,m)=randi([24,26],1);
elseif m==7
MutChrom(n,m)=randi([27,28],1);
elseif m==8
MutChrom(n,m)=randi([29,40],1);
else
MutChrom(n,m)=randi([41,53],1);
end
end
end
end
In case anyone comes up with something better i would be happy to throw it away..
Thanks,
Mike
