An Improved Tabu Search Algorithm for Job Shop Scheduling Problem Trough Hybrid Solution Representations

Job shop scheduling problem (JSP) is an attractive field for researchers and production managers since it is a famous problem in many industries and a complex problem for researchers. Due to NP-hardness property of this problem, many meta-heuristics are developed to solve it. Solution representation (solution seed) is an important element for any meta-heuristic algorithm. Therefore, many resear...

A New Analytical Solution for Determination of Acceptable Overall settlement of Heap Leaching Structures Foundation

There are some artificial and natural materials on foundation of heap leaching structures. Geomembrane liner is the most important artificial isolated layer of these structures. The thickness of this layer is about 1 to 2 mm. Foundation overall settlement of such structures changes the primary length of the geomembrane layer. If the strain of geomembrane is more than allowable one, the layer wi...

The never-ending search of an acceptable compromise for pancreatic lipase standardisation.

Human pancreatic lipase (HPL) is a single-chain glycoprotein with a molecular weight of 48,000 Da (1) . Its concentration in the pancreas is approximately 9000-fold greater than in other tissues, and the concentration gradient between pancreas and serum is approximately 20,000-fold (2) . For full catalytic activity and greatest specifi city, the presence of bile salts (such as sodium deoxychola...

FUZZY GRAVITATIONAL SEARCH ALGORITHM AN APPROACH FOR DATA MINING

The concept of intelligently controlling the search process of gravitational search algorithm (GSA) is introduced to develop a novel data mining technique. The proposed method is called fuzzy GSA miner (FGSA-miner). At first a fuzzy controller is designed for adaptively controlling the gravitational coefficient and the number of effective objects, as two important parameters which play major ro...
