We call this type of solution an approximate solution and the corresponding algorithm a polynomial time approximation algorithm most combinatorial optimization problems of great practical relevance are indeed computationally intractable in the above sense in formal terms they are classified as np hard optimization problems. Buy complexity and approximation combinatorial optimization problems and their approximability properties on amazoncom free shipping on qualified orders. Combinatorial optimization problems and their approximability properties the need to solve difficult optimization problems is another reason that forces us to deal with approximation in particular when a problem is computationally hard i e the only way we know to solve it is by making use of an algorithm that runs in exponential time .
