On the mixing set with a knapsack constraint
http://lsec.cc.ac.cn/~dyh/file/publication/131.pdf WebIn Sec. II, we define graph theory terms that will be used throughout the paper.Next, in Sec. III, we discuss how to map arbitrary combinatorial optimization problems to polynomial unconstrained binary optimization problems (PUBOs) by dualizing constraints, and apply the method to MaxCut, Maximum Independent Set, and a general combinatorial …

We study the convex hull of the continuous knapsack set which consists of a single inequality constraint with \ (n\) non-negative integer and \ (m\) non-negative bounded continuous ... 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]. The polyhedron conv n x2f0;1gn: Xn i=1 a ix i b o is called a knapsack ...
