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.
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.

Compact Genetic Algorithm on Quantum computers
This work presents an example of programming a quantum computer. The
compact genetic algorithm is used as a target as it is powerful and
popular method in evolutionary computation. This paper demonstrates
the enhancement in terms of solution quality and speed introduced by
quantum computation. The simulation of quantum computing is carried out
for solving a problem using the compact genetic algorithm. The exponential
speed up over a classical computer is demonstrated.
Keywords: Genetic algorithms,
Compact Genetic Algorithms, Quantum Computers.
