Outline of Final Research Achievements

Most research in algorithms since the 1970s has been for single processor machines, resulting in a vast amount of sophisticated and robust software. Unfortunately most of this software profits very little when run on the now prevalent multiprocessor hardware. The redesign and re-implementation for all of this software will be an extremely time consuming and expensive task. The purpose of this research is to efficiently parallelize algorithms without any essential change to their existing implementation. This is achieved by adding parallelization as a wrapper to the existing code. This technique will be applied in particular to certain tree search algorithms used in optimization, artificial intelligence and machine learning. International research collaboration is a major part of our project.

Academic Significance and Societal Importance of the Research Achievements

この期間中に、合計12の査読付き国際ジャーナル論文が発表されました。木検索方法の効率的な並列化を可能にするmtsパッケージを作成して配布しました。 lrslib多面体計算パッケージの範囲が大幅に拡張され、ほとんどの関数の並列化が含まれるようになりました。 lrslibは現在DebianLinuxの標準部分であり、研究者によって広く使用されています。特に、mplrsは現在、ほとんどの大規模な入力で利用できる最速の頂点列挙/凸包並列プログラムです。私たちのプログラムはすべてオープンソースです。
