Yices 2.2 [chapter]

Bruno Dutertre
2014 Lecture Notes in Computer Science  
The first version of Yices was released in 2006 and has been continuously updated since then.  ...  We present the tool's architecture and discuss the algorithms it implements, and we describe recent developments such as support for the SMT-LIB 2.0 notation and various performance improvements.  ...  Yices also includes two specialized solvers for the difference-logic fragments of linear arithmetic. These two solvers rely on a variant of the Floyd-Warshall algorithm.  ...
