Hybrid Variable Neighborhood HyperHeuristicsfor Exam Timetabling Problems (2005)
Presentation / Conference
Qu, R., & Burke, E. (2005, August). Hybrid Variable Neighborhood HyperHeuristicsfor Exam Timetabling Problems. Paper presented at The Sixth Metaheuristics International Conference 2005, Vienna, Austria

This paper presents our work on analysing the high level search within a graph based hyperheuristic. The graph based hyperheuristic solves the problem at a higher level by searching through permutations of graph heuristics rather than the actual solu...

Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference
Gordo, E., Chen, G. Z., & Fray, D. J. (2005, February). Electro-deoxidation of solid chromium oxide in molten chloride salts. Paper presented at TMS Annual Meeting 2005, San Francisco, California, U.S.A

Chromium is industrially produced by aluminothermic reduction of Cr 2O3 or electrodeposition from the aqueous NH 4Cr(SO4)2 solution. The former makes more a expensive product than an electrolytic method because the reductant, aluminium, is produced b...
