Constraints in GAMULTIOBJ using bitstring

Hi guys,

I'm trying to solve an optimization binary problem using the gamultiobj function provided by Matlab but everytime I run it I get a warning message saying that since I'm using a bitstring population then all supplied constraints are ignored. I went throught the documentation and ideed it says that constraints are only implemented for the default population type, i.e. doubleVector. So my questions is, is there anyway I can add/give my constraints to the solver?
