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. http://lsec.cc.ac.cn/~dyh/file/publication/131.pdf
