Typedef IlcChooseFloatIndex

This C++ type represents a pointer to a function that takes an array of constrained floating-point variables and returns an integer.

In its search primitives for finding solutions, Solver lets you set parameters for choosing the order in which constrained variables are bound. You do so by means of choice functions called criteria.

The choice functions for constrained floating-point expressions (that is, instances of IlcFloatExp or its subclasses) should have a signature of this type.
