The analysis of models of evolutionary games requires explicit consideration of both evolutionary game rules and mutants which infinitesimally break these rules. For example, the Scotch Auction is an evolutionary game which lacks both a rule-obeying evolutionarily stable strategy and an asymptotically stable polymorphism of rule-obeying strategies. However, an infinitesimal rule-breaking, or ch...

Recent study has shown that the application of a Scotch Yoke crank mechanism to a reciprocating internal combustion engine reduces the engine’s size and weight and generates sinusoidal piston motion that allows for complete balance of the engine. This paper describes detailed investigation of the performance of a linear bearing assembly, which is one of the key components of the Scotch Yoke mec...

Scotch is a software package for sequential and parallel graph partitioning, static mapping and sparse matrix ordering, and for sequential mesh/hypergraph ordering. It has been designed in a highly modular way, so that new methods can be easily added to it, in order for it to be used as a testbed for the design of new partitioning and ordering methods. This paper discusses the internal structur...
