Currently, approximation algorithms seem to be the most successful approach for solving hard optimization problems Immediately after introducing NP-hardness (completeness) as a concept for proving the intractability of computing problems, the following question was posed:``If an optimization problem does not admit any efficient1 algorithm computing an optimal solution, is there a possibility to efficiently compute at least an approximation of the optimal solution?''
