http://users.iems.northwestern.edu/~simge/Preprints/Mix-MP2012.pdf WebA knapsack constraint is a linear constraint of the form P n i=1 a ix i b, where band nare positive integers and a 2Zn +. Any linear inequality involving binary variables can be converted into a knapsack constraint, by complementing variables with negative coe cients [23].

On the Mixing Set with a Knapsack Constraint

WebKnapsack Constraints. A knapsack constraint is an alternate to a cardinality constraint (the default in apricot) where each element has a cost and the selected items cannot exceed a total budget. The name (according to Krause (2012)) is a reference to the knapsack problem where one maximizes a modular function subject to a modular cost.
