NettetThe integer feasibility problem is NP-complete: A x = b, x ≥ 0, x integer A contains elements in R If we restrict this: A contains only elements in: { 1, 0 } { 1, 0, − 1 } N Z Does this change anything in term of hardness? Can all these problems be reduced to … Nettet12. feb. 2016 · NP-hard refers to the complexity of algorithms in the worst case. For most NP-hard problems, we have effective algorithms (heuristic or exact) that perform well most of the time, even if they do not perform well in the worst case. ILP is therefore a very useful tool in practice, even if there are some problems that it doesn't do well on. top 10 best smash bros players

NettetWe construct a special class of indefinite quadratic programs, with simple constraints and integer data, and show that checking (a) or (b) on this class is NP-complete. As a corollary, we show that checking whether a given integer square matrix is not copositive, is NP-complete.

His section 1.1, Definition 4 is a clear example: "A problem L is P-Hard iff a polynomial algorithm for L implies P = NP." As D.W. asserts, this eliminates the discrepancy between Sahni and G&J: the problem is NP-hard/-complete, depending on the signs of the constraint coefficients. pibby jake the dog
