description: <strong>This record will soon be published.</strong><strong>Sayre Sankano and Musa Molloh</strong>

The relationship between Musa Molloh and Sayre Sankano was very amicable.  Sayre Sankano was not only a friend but was Musa’s marabout and advisor. Sayre Sankano studied the Koran at Fouta under Foday Hayib Mamadu Konteh, the father of Foday Musa Konteh. Musa Molloh completely depended on him. In fact, Musa Molloh presented him with three of his sons and also two wives. Before Musa Molloh fought with his brother Dikori Kumba at Patta, he sent for Sayre to support him.  He was provided with spiritual water in order to charm and beguile Dikori and his men. Dikori was later ambushed and killed by Musa Molloh’s men.

title: Advanced constraint programming formulations for additive manufacturing machine scheduling problems

description: In comparison with traditional subtractive manufacturing techniques, additive manufacturing (AM) enables fabricating complex parts through a layer-by-layer process. AM makes it possible to produce one-piece and lightweight functional products, which are traditionally made from several parts. This paper introduces constraint programming (CP) models to minimise makespan in single, parallel identical and parallel unrelated AM machine scheduling environments for selective laser melting. Alternative CP formulations are explored to improve efficiency. The proposed CP model significantly benefits from the introduction of interval variables to replace binary assignment variables, and pre-definitions to narrow the search space, resulting in increased search performance. A computational study has been conducted to compare the performance of our proposed CP model with both a mixed-integer programming and a genetic algorithm from existing literature, evaluating improvements made to its search capability. Computational results indicate that the proposed CP model can obtain high-quality solutions in a timely manner even for several large-size instances.
