Minimization of Keane’s Bump Function by the Repulsive Particle Swarm and the Differential Evolution Methods

چکیده
Source: Hacker, Eddy and Lewis (2002) A visual appreciation of Keane’s two-dimensional (m=2) bump function may be obtained from the graphical presentation (Fig.-1; Hacker et al., 2002). As the dimension (m) grows larger, the optimum value of the function becomes more and more difficult to obtain. Keane (1994) observed that for m=20 the value of min[f(x)] could be about -0.76 and for m=50 it could be about -0.835 but did not know this to be the case.

Optimization of Minimum Quantity Liquid Parameters in Turning for the Minimization of Cutting Zone Temperature
The use of cutting fluid in manufacturing industries has now become more problematic due to environmental pollution and health related problems of employees. Also the minimization of cutting fluid leads to the saving of lubricant cost and cleaning time of machine, tool and work-piece. The concept of minimum Quantity Lubrication (MQL) has come in to practice since a decade ago in order to overco...
