On-time shipment delivery is critical for just-in-time production and quick response logistics. Due to uncertainties in travel and service times, on-time arrival probability of vehicles at customer locations can not be ensured. Therefore, on-time shipment delivery is a challenging job for...

Tabu search is a greatly successful metaheuristics, as illustrated through numerous publications showing its use for a range of difficult optimization problems. The tabu search literature is to a certain degree characterized by papers introducing new variations of the search, either presenting...

The primary objective of software testing is to locate bugs as many as possible in software by using an optimum set of test cases. Optimum set of test cases are obtained by selection procedure which can be viewed as an optimization problem. So metaheuristic optimizing (searching) techniques have...

Sensors form an effective wireless network for the surveillance of a region. Ensuring coverage is an important issue in wireless sensor network design. This paper focuses on an application where sensors are used to detect intruders. The defender wants to determine the best locations of the...

Since the first appearance of the Genetic Programming (GP) algorithm, extensive theoretical and application studies on it have been conducted. Nowadays, the GP algorithm is considered one of the most important tools in Artificial Intelligence (AI). Nevertheless, several questions have been...
