Research Highlight

Hardware Compact Genetic Algorithm

Genetic Algorithm is an optimization technique based on probabilistic search.  It is a sub-field of Artificial Intelligence. It is widely used in industry because it is simple and effective.  Hardware Compact Genetic Algorithm is an embodiment of the algorithm into digital circuits, achieving 1000 times speed up over the software incarnation.
Keywords: Compact Genetic Algorithm, Hardware implementation.
ref Aportewan and Chongstitvatana, 2001 #5

Coincidence Algorithm

Coincidence Algorithm is an optimization algorithm for combinatorial problems.  There are many uses in industry such as scheduling assembly line, inventory control, logistics etc.  A unique characteristic of Coincidence Algorithm is its use of the negative examples to improve the quality of the solution.  Presently, negative-correlation learning has been acknowledge as one of the new promising method in optimization and machine learning. 
Keywords: Combinatorial optimization, scheduling, negative learning.
