How to run problem structure form with a ga algorithm=

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?
