As programmable logic controllers(PLCs) have been used in safety-critical applications, testing of PLC applications has become important. The previous PLC-based software testing te...
Any VR scenario should offer a certain degree of nonlinearity or openness regarding the story progress as a consequence of the interaction with the user. In this paper we propose ...
We introduce a simple game family, called Constraint Logic, where players reverse edges in a directed graph while satisfying vertex in-flow constraints. This game family can be in...
Identifying user-dependent information that can be automatically collected helps build a user model by which 1) to predict what the user wants to do next and 2) to do relevant pre...
We describe a class of problems motivated by numerous real-world applications where there is a collection of objects that have both a cost and a value, but where some of those obj...
