Teamwork is a critical capability in multi agent envi ronments Many such environments mandate that the agents and agent teams must be persistent i e exist over long periods of time Agents in such persistent teams are bound together by their long term common interests and goals This paper focuses on exible teamwork in such per sistent teams Unfortunately while previous work has investigated exib...

Including duplicate tasks in the mining process is a challenge that hinders the process discovery as algorithms need an extra effort to find out which events of the log belong to which transitions. To face this problem, we propose an approach that uses the local information of the log to enhance an already mined model by performing a local search over the potential tasks to be duplicated. This ...

The Costas Array Problem is a highly combinatorial problem linked to radar applications. We present in this paper its detailed modeling and solving by Adaptive Search, a constraint-based local search method. Experiments have been done on both sequential and parallel hardware up to several hundreds of cores. Performance evaluation of the sequential version shows results outperforming previous im...

The equitable dispersion problem consists in selecting a subset of elements from a given set in such a way that a measure of dispersion is maximized. In particular, we target the max-mean dispersion model in which the average distance between the selected elements is maximized. We first review previous methods and mathematical formulations for this and related dispersion problems and then propo...
