Due to the NP completeness of many combinatorial optimization problems, they are quite difficult to be solved analytically, and exact search algorithms such as branch and bound may degenerate to complete enumeration, and the CPU time needed to solve them may grow exponentially in the worst case. However, in the present study we solve the ATSP instances without transforming into STSP instances. Computer Science > Data Structures and Algorithms By using OWA, the traditional min-max approach to combinatorial optimization problems with uncertain costs, often regarded as too conservative, can be generalized. Combinatorial Optimization - Algorithms and Complexity. The computational complexity and approximability of the problem of minimizing OWA for the considered class of problems are investigated and some new positive and negative results in this area are provided. The TSP is a NP-complete combinatorial optimization problem [3]; and roughly speaking it means, solving instances with a large number of nodes is very difficult, if not impossible. In many practical situations heuristic algorithms reliably give satisfactory solutions to real-life instances of optimization problems, despite evidence from computational complexity theory that the problems are intractable in general. Among these patterns, the real encoding has been shown to have more capability for complex problems (Andrzej [26]).

Since ATSP instances are more complex, in many cases, ATSP instances are transformed into STSP instances and subsequently solved using STSP algorithms [4].
