We present a detailed experimental investigation of the easy-hard-easy phase transition for randomly generated instances of satisfiability problems. Problems in the hard part of the phase transition have been extensively used for benchmarking satisfiability algorithms. This study demonstrates that p

The problem of locating a set of depots in an arc routing context (with no side constraints) is addressed. In the case of one depot, it is shown that the problem can be transformed into a Rural Postman Problem (RPP). In the case of a set of depots, the problem is also reduced to an RPP if there are
