Interface Summary

IConstr	The most general abstraction for handling a constraint.
IOptimizationProblem	Represents an optimization problem.
IProblem	Access to the information related to a given problem instance.
ISolver	This interface contains all services provided by a SAT solver.
IteratorInt	Iterator interface to avoid boxing int into Integer.
IVec<T>	An abstraction on the type of vector used in the library.
IVecInt	An abstraction for the vector of int used on the library.

Exception Summary

ContradictionException	That exception is launched whenever a trivial contradiction is found (e.g.
TimeoutException	Exception launched when the solver cannot solve a problem within its allowed time.
