is available and still an upper-bound solution. Key words: rectangular bar forging; bulging; strain rate vector; inner-product; golden section search 1 Introduction Forging a bar with flat tools is one... effective factor. It is obviously that the stress effective factor nσ is a function of A, m, b0/h and l/h, also is a analytical solution. The optimum values of A and nσ by the golden section search......

A free search algorithm with double populations for QoS multicast routing KONG Sun(孔笋), CHEN Zeng-qiang(陈增强) (Department of Automation, Nankai University, Tianjin 300071, China) Abstract: In this paper, we introduce a modified free search (FS) algorithm to solve QoS multicast routing problem. Based on basic FS, the algorithm introduces an auxiliary population to retain the suboptimal solutions......

; accepted 8 June 2017 Abstract: A neighborhood search algorithm was proposed to simultaneously schedule the waste removal quantity and the equipment fleet profile over the mine life for open pit mines. An initial search domain was first defined and a good schedule was obtained as the current best schedule by searching in this domain. Then, progressively narrower neighborhood search domains were......
