Query: If global search found no solution

Hello,

is there a way to do a query, if the global Search Alg (or MultiStart Alg) was not able to find a solution?

I have an Algorithm and i use Global Search, and sometimes i get the message:

0 local solver runs converged with a positive local solver exit flag.

But global Search still gives a solution back but i do not want to "add" the point (to my further Alg) if this happens.

Same question for fmincon. I get the message:

Converged to an infeasible point.

And i would like to not "add" the point (to my further Alg) if fmincon converged to an infeasible point.

So i want to do something like

if (fmincon converged to an infeasible point)
    ....
end

run the global search with additional diagnostic outputs to see if a valid solution was found,

[x,fval,exitflag,output,solutions] = run(gs,problem)
