Description:
 def add_cut(problem, indicators, bound, Constraint):
 """ Add an integer cut to the problem. Ensure that the same solution involving these indicator variables cannot be found by enforcing their sum to be less than before. Parameters problem : optlang.Model Specific optlang interface Model instance. indicators : iterable Binary indicator `optlang.Variable`s. bound : int Should be one less than the sum of indicators. Corresponds to P - 1 in equation (14) in [1]_. Constraint : optlang.Constraint Constraint class for a specific optlang interface. References .. [1] Gevorgyan, A., M. G Poolman, and D. A Fell.
