2. Fractional graph coloring can be viewed as the linear programming relaxation of traditional graph coloring.
3. Linear programming relaxation is a standard technique for designing approximation algorithms for hard optimization problems.
4. MINTO is a software system that solves mixed integer programming problem by a branch and bound algorithm with linear programming relaxations.
5. For example, a linear programming relaxation of an integer programming problem removes the integrality constraint and so allows non-integer rational solutions.
6. It's difficult to find linear programming relaxation in a sentence. 用linear programming relaxation造句挺難的
7. Thus, in this example, the linear programming relaxation has a value differing from that of the unrelaxed 0-1 integer program.
8. One can turn the linear programming relaxation for this problem into an approximate solution of the original unrelaxed set cover instance via the technique of randomized rounding.
9. Couenne is an implementation of a branch-and-bound where every subproblem is solved by constructing a linear programming relaxation to obtain a lower bound.
10. Conversely, if we can prove that a linear programming relaxation is integral, then it is the desired description of the convex hull of feasible ( integral ) solutions.
11. Certain configurations within these problems can be used to define facets of the polytope describing a linear programming relaxation of the problem; these facets are called M鯾ius ladder constraints.
