Hi,
I'm trying to use ga to solve two problems: Mixed integer linear problem and a Mixed integer non linear problem.
I have the problem formulated in the problem strucure. Below are the main parts:
%Parametros
% ------- Decision Variables ------------------------------
Y = optimvar('Y',I,J,'Type','integer','LowerBound',0,'UpperBound',1);% Se o cliente i vai no carro j
V = optimvar('V',J,'Type','integer','LowerBound',0,'UpperBound',1); % Se o carro j esta a ser usado
P = optimvar('P',I,'Type','integer','LowerBound',0,'UpperBound',1); % Se o cliente i vai em partilhado
%Objective function
objfun = sum(V,'all')*preco_dedicado + sum(P,'all')*preco_partilhado ;
temp_prob.Objective = objfun;
%Restrictions
%temp_prob.Constraints.aloc_obrigatoria = aloc_obrigatoria;
temp_prob.Constraints.aloc_obrigatoria_sup = aloc_obrigatoria_sup;
temp_prob.Constraints.aloc_obrigatoria_inf = aloc_obrigatoria_inf;
temp_prob.Constraints.const_X_1 = const_X_1;
temp_prob.Constraints.const_X_2 = const_X_2; temp_prob.Constraints.const_X_3 = const_X_3;
temp_prob.Constraints.veiculo_usado = veiculo_usado;
temp_prob.Constraints.combinacao_possivel = combinacao_possivel;
temp_prob.Constraints.condicao_tempo = condicao_tempo;
%Call Solver
problem = prob2struct(temp_prob);
[x,fval] = ga(problem);
It gives me the following error:
Error using separateOptimStruct (line 25)
Use INTLINPROG function for this problem
structure.
Error in ga (line 263)
[fun,nvars,Aineq,bineq,Aeq,beq,lb,ub,nonlcon,intcon,rngstate,options]
= separateOptimStruct(fun);
Error in modelo_nors_revisto_ga_linear (line 121)
[x,fval] = ga(problem);
Can anyone help?
