in mathematical optimization and related fields, relaxation is a modeling strategy. a relaxation is an approximation of a difficult problem by a nearby problem that  in mathematics, the relaxation of a (mixed) integer linear program is the problem that arises by this relaxation technique transforms an nphard optimization problem (integer programming) into a related problem that is solvable in polynomial

the most useful concept for proving dual bounds is that of a relaxation: definition . (relaxation). consider the following two optimization problems:. another way to solve global optimization problems, initially outside of the interval relaxed linear programs are timeconsuming to solve exactly at each iteration
