% ObjVal = tspfun(Phen, Dist)
% Implementation of the TSP fitness function
%	Phen contains the phenocode of the matrix coded in adjacency
%	representation
%	Dist is the matrix with precalculated distances between each pair of cities
%	ObjVal is a vector with the fitness values for each candidate tour (=each row of Phen)
%

function ObjVal = tspfun(Phen, Dist);

	ObjVal=Dist(Phen(:,1),1);
	for t=2:size(Phen,2)
		ObjVal=ObjVal+Dist(Phen(:,t),t);
	end
