2. List of NP-complete problems - Wikipedia

   en.wikipedia.org/wiki/List_of_NP-complete_problems

   Quadratic programming (NP-hard in some cases, P if convex) Subset sum problem [3]: SP13 Variations on the Traveling salesman problem. The problem for graphs is NP-complete if the edge lengths are assumed integers. The problem for points on the plane is NP-complete with the discretized Euclidean metric and rectilinear metric.

3. Linear programming relaxation - Wikipedia

   en.wikipedia.org/wiki/Linear_programming_relaxation

   Two 0–1 integer programs that are equivalent, in that they have the same objective function and the same set of feasible solutions, may have quite different linear programming relaxations: a linear programming relaxation can be viewed geometrically, as a convex polytope that includes all feasible solutions and excludes all other 0–1 vectors ...

4. Integer programming - Wikipedia

   en.wikipedia.org/wiki/Integer_programming

   Integer programming is NP-complete. In particular, the special case of 0–1 integer linear programming, in which unknowns are binary, and only the restrictions must be satisfied, is one of Karp's 21 NP-complete problems. [1] If some decision variables are not discrete, the problem is known as a mixed-integer programming problem. [2]

   All of the study participants walked about three miles for four days a week. Those in the fastest group walked about 4.1 miles an hour and exercised for about 45 minutes a day. Women in the slower ...

8. Polynomial-time reduction - Wikipedia

   en.wikipedia.org/wiki/Polynomial-time_reduction

   A problem that belongs to NP can be proven to be NP-complete by finding a single polynomial-time many-one reduction to it from a known NP-complete problem. [6] Polynomial-time many-one reductions have been used to define complete problems for other complexity classes, including the PSPACE -complete languages and EXPTIME -complete languages.
