Patrick Kasting, Michael R. Hansen, Steen Vester
2016 Proceedings of the 28th Symposium on the Implementation and Application of Functional Programming Languages - IFL 2016  
Imperative features of F # proved useful in two places: Hash tables and arrays were used in the representations of the railway network model and the reachability game.  ...  In this work, we show the feasibility of using functional programming (more specifically F # ) in connection with gamebased methods for synthesis of correct-by-construction controllers (also called signaling  ...  We consider the following problem: Synthesis of correct signaling plans for railway networks Game-Based Synthesis The synthesis problem is solved using game-based methods: In a reachability game, two  ...
