A Subtour Elimination Constraint for Non-simpl e Circuit Problems A Subtour Elimination Constraint for Non-simpl e Circuit Problems Seiji, Kataoka Seiji, Kataoka [一般論文] Non-simple circuit, Orienteering problem, Subtour elimination constraint, Callback function provided in solvers In various problems on graphs to find the optimal path or circuit, feasible solutions are normally assumedto be simple. In reality, however, one-way or return roads, bridges connecting enclaves, etc. often lead to multiplepasses through the same points or roads, i.e. a non-simple path or circuit. The difficulty in considering a non-simplepath or circuit is that conventional subtour elimination constraints are of no use. Taking the orienteering problem as atarget, we newly develop a subtour elimination constraint that works directly against non-simple type problems, andshow its effectiveness in computational experiments. ------------------------------ This is a preprint of an article intended for publication Journal of Information Processing(JIP).
