Gurobi Optimization社は、数理最適化ソルバーGurobiのバージョン8.0を、リリースしました。最新バージョンでは、総体的な求解性能の改良およびGurobi 計算サーバとGurobiインスタントクラウド への機能拡張が行われました。
Gurobi Optimization社の共同創設者で、CEOのEdward Rothberg博士は、「我々の最新のリリースであるバージョン8.0では、Gurobi 計算サーバとGurobi インスタントクラウド にユーザを興奮させるような新機能が提供され、かつ、ソルバーの速度と性能の限界を超えることにまたも成功しました。」と述べています。
Gurobi 社の数千もの実世界のモデルから構成されるテストライブラリによる性能テストで、すでに産業界の最先端を行くGurobi バージョン7.5と比較して、大幅な求解性能の向上があったことが示されています。混合整数計画法(MIP)モデルでは、バージョン7.5と比べて総体的に16%の高速化に成功し、また、求解に100秒以上かかるような難しい問題では26% 高速に解けることが示されました。
線形計画法(LP)モデルでは、V.8.0の双対単体法アルゴリズムにより、総体的に10%も高速化が実現されています。このクラスのモデルでは、とても顕著な性能向上であると言えます。
「Gurobi 8.0の利用により、我々の多くの難しいモデルにおいて、大幅な性能向上を経験しました。」とPortchain 社の解析部門の責任者であるMichael Lindahl氏は、述べています。
計算サーバが独立してパッケージ化され、通常のコンポーネントと分けてインストールすることができるようになりました。新しいパッケージは、以下の機能を含んでいます。
