Get the solution value of a nonlinear constraint.

Solution value or 0.

The following prints the solution values of a nonlinear constraint and a nonlinear expression.

writeln("Evaluation of an expression: ", getsol(abs(x*y)+5*z^3)) 

This function returns the evaluation of a nonlinear constraint using the current solution values of its variables. Note that the solution value of a variable is 0 if the problem has not been solved or the variable is not contained in the problem that has been solved.

maximize/ minimize, copysoltoinit.
