Theory on the evolution of behavior generally neglects such opportunity-based adaptation. Using a spatial individual-based model we...

It is of significant benefit to man-machine communication and can assist in the automatic processing of handwritten documents. It is a subtask of the Optical Character Recognition (OCR), whose domain can be machine-print only.The introduced system is a character-based recognition an...

Design patterns are graceful solutions to specific software design problems. However, choosing proper design patterns for given software design problems might not be an easy task especially for novice developers. The design patterns searching tools are therefore needed to solve the problem. One major problem of the existing researches in this field is the indexing problem. This paper aims to so...
