Approximation algorithmPerformance guaranteeIn this paper, we study the path version of the Traveling Salesman Problem with the edge cost function satisfying a "relaxed" form of triangle inequality called the biased triangle inequality. We denote this problem as the Biased-TSP-Path . In this paper,...
