For more than two machines, and when preemption is forbidden, the computation of minimum makespan schedules for the open-shop problem is NP-hard. Compared to the flow-shop and the job-shop, the open-shop has free job routes which lead to a much larger solution space, to smaller gaps between the...

Intelligent control techniques for robotic systems have been used with some success in a wide variety of applications. In this paper, we construct a method for the intelligent control system of a robot using the fuzzy behavior-based control, which decomposes the control system into several...

When handling tree networks, a number of researchers have tried using the pruefernumberrepresentation for encoding the network, but GAs often degraded or broke down when used onthis encoding. This paper investigates the locality of the pruefernumber, which can be describedas the relatedness of...
