Simple algorithms can\u2019t solve these problems anywhere near optimally. But if we used advanced algorithms, we get better solutions that increase profit, reduce our ecological footprint and improve customer satisfaction.<\/div>\n<div>In this session, I will introduce constraint optimization, demo a few use cases, use weighted hard and soft constraints to formalize business goals, walk through example code in Java of our open source constraint solver OptaPlanner, cover real-time continuous planning and teach algorithms such as Exhaustive Search (Brute Force), Construction Heuristics (First Fit) and Local Search (Tabu Search, Simulated Annealing)<\/div>\n<div class=\"HOEnZb\">\n<div class=\"adm\">\n<div id=\"q_234\" class=\"ajR h4\"><\/div>\n<\/div>\n<\/div>\n<\/div><div class=\"fusion-clearfix\"><\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-2 fusion_builder_column_1_3 1_3 fusion-one-third fusion-column-last\" style=\"width:33.333333333333%;width:calc(33.333333333333% -
