## Abstract We study the complexity of two inverse shortest paths (ISP) problems with integer arc lengths and the requirement for uniquely determined shortest paths. Given a collection of paths in a directed graph __D__ = (__V__, __A__), the task is to find positive integer arc lengths such that th
