Abstract- This paper presents the implementation of a
number of elitist schemes for a low cost printed circuit
board (PCB) inspection system. This strategy also
aims to explore the role of tournament and roulette-
wheel in improving the existing system when using a
deterministic selection scheme. In this system, GA is
used to detect rotation angle and displacement of PCB
placed arbitrarily on a conveyor belt passing under the
camera. Deterministic, tournament and roulette-wheel
selection scheme have been compared in terms of max-
imum fitness, rate of accuracy and computation time.
The finding shows that deterministic out-performed the
other two schemes in all categories and still prove to be
