題名 平行疊代法解互補問題
Parallel Iterative Methods for Complementarity Problem作者 張泰生 貢獻者 楊建民
張泰生日期 1989 上傳時間 4-五月-2016 14:31:26 (UTC+8) 摘要 摘要 本論文係研究和發展平行疊代法(parallel iterative method)以解決數學規劃(mathematical programming)中之互補問題(complementarity problem)。互補問題源自解決國防軍事、工程、經濟及管理科學等領域之應用,而由於近年來各種超級或平行電腦不斷地創新,使得發展平行演算法,以充分並有效地應用超級或平行電腦來解決大型科學計算的問題日趨重要。 在本篇論文中,我們分別探討線性互補問題以及非線性互補問題,首先我們發展出一半非同步(semi-asynchronous)法來解線性互補問題,此法之特性在於其能大幅地減低因同步法所造成處理機閒置(idling)之冗額成本(overhead);同時,也放寬了非同步法對問題所加諸之限制,因而擴大了半非同步法所能應用之範圍。我們也建立了有關該法收斂性(convergence)之理論根據。此外,線性互補問題之探討,實為進一步研究非線性互補問題之基礎。 其次,我們提出一個整體性之架構,探討平行牛頓法(Newton method)及其各種變形(variations)來解決各種非線性互補問題,比較並研究各種方法的特性、限制及執行效率。 然後,針對上述各種演算法,我們在教育部電算中心之IBM 3090上發展並模擬各法之平行運算,經由廣泛地測試執行,以獲得具體之數值結果,來檢驗各平行演算法之效率,並比較研究各法之適用性與優劣。最後,我們也提出一些相關之問題,以供未來後續研究之參考。 參考文獻 參考文獻: [1] M.
