在本文中,我们考虑无限树上的线性算术约束,其节点用非负实数标记。这些限制是在面向对象程序的资源推断背景下出现的,但应该具有独立的意义。这些约束系统的可满足性是否是可判定的,目前尚无定论。然而,对于从应用程序到资源推理的受限片段,我们能够提供基于常规树的启发式决策过程。我们还观察到,在这些无限树上优化线性目标的相关问题属于凸优化领域。
In this paper we consider linear arithmetic constraints over infinite trees whose nodes are labelled with nonnegative real numbers. These constraints arose in the context of resource inference for object-oriented programs but should be of independent interest. It is as yet open whether satisfiability of these constraint systems is at all decidable. For a restricted fragment motivated from the application to resource inference we are however able to provide a heuristic decision procedure based on regular trees. We also observe that the related problem of optimising linear objectives over these infinite trees falls into the area of convex optimisation.
