The focus of this research was to formulate optimization model 16-bar trussesalong with stress, stability and deflection constraints. derivative free methods were used for theoptimization engineering design problems. These basically designed forunconstrained In formulated truss problems the constraints werehandled by using exterior penalty functions. results obtainedby MATLAB which demonstrated...

A pattern database is a lookup table that stores an exact evaluation function for a relaxed search problem, which provides an admissible heuristic for the original search problem. In general, the larger the pattern database, the more accurate the heuristic function. We consider how to build large pattern databases that are stored in external memory, such as disk, and how to use an externalmemor...

This paper presents an efficient search algorithm for fast block matching motion estimation(ME) for video applications. The algorithm uses two patterns for initial search and refined local search. For initial search, the proposed algorithm uses a square pattern adaptively by selecting the step size based on Maximum Absolute Value of predicted motion vector. This search pattern is aimed to reduc...
