I am trying to generate vertices for different polygons using constraint programming.
I want to only get vertices that will not lead to self-intersecting polygons.
How would I set the constraint so only vertices for simple polygons are generated??

Unless you state the integrity of the coordinates of the vertices, you need a solver that handle floating point decision variables. I never heard about CP solver implementing complex number as decision variables.
The geometrical conditions that defines a simple polygon will lead to inequalities or dis-equalities between numerical expressions. I would suggest to add an intolerance parameter that allows to forbid polygon that are almost complex.
Hope that helps

I am not implementing complex numbers, i am generating normal vertices but when visualized, some of the polygons are self-intersecting e.g a star. I would like to eliminate such cases so that I get vertices that will make non self-intersecting polygons. Thank you
