✦ Synopsis


The goal of troubleshooting is to find an optimal solution strategy consisting of actions and observations for repairing a device. We assume a probabilistic model of dependence between possible faults, actions, and observations; the goal is to minimize the expected cost of repair (ECR). We show that the task of finding an optimal solution strategy is NP hard for various troubleshooting models; therefore, approximate algorithms are necessary.

## Abstract We reconsider some classical natural semantics of integers (namely iterators of functions, cardinals of sets, index of equivalence relations) in the perspective of Kolmogorov complexity. To each such semantics one can attach a simple representation of integers that we suitably effectivi
