3.發(fā)表學術論文及科研成果

代表性的科研成果：

[1]二次指派問題方面的模型被國際頂級期刊《Operations Research》上的文章《Three Ideas for the Quadratic Assignment Problem》(作者Fischetti,Monaci和Salvagnin)用來求解了一類大規(guī)模問題，該文8次引用我們的模型，并稱其為 Xia-Yuan model.被頂級期刊《INFORMS Journal on Computing》上的文章《The Robust (Minmax Regret) Quadratic Assignment Problem with Interval Flows》(作者Feizollahi 和 Averbakh) 一文11次引用，稱其為Xia-Yuan linearization.

[2]獨立獲得了正交相似集凸包絡的完美刻畫。06年Ding和Wolkowicz 在一手稿中研究了矩陣的正交相似集的凸包絡，給出了一些等價刻畫，但是這些等價集合要么是無窮多個線性約束要么是非線性非凸約束，因而只能近似計算。我們巧妙構造性證明了正交相似集的凸包絡可以由有限個線性矩陣不等式(LMI) 等價完整刻畫! Ding 和Wolkowicz的論文在09年《Mathematics of Operations Research》正式發(fā)表時用一個評論談及該項工作稱``We failed to recognize this point in our initial work''

[3]回答了Zhu于2003年在《Journal of Optimzation Theory and Application》上提出的關于0-1與連續(xù)二次規(guī)劃關聯(lián)的一個公開問題。

[4]回答了Pinar和Teboulle于2006年在《RAIRO Operations Research》上提出的關于L1范數(shù)約束非凸二次規(guī)劃的兩個公開問題。

[5]Hiriart-Urruty于2007在《SIAM Review》提出了14個公開問題。其中第11個公開問題是問兩個二次正定型乘積的Legendre-Fenchel conjugate，在假定函數(shù)是凸的前提下，Zhao于2010年在《SIAM Journal of Matrix Analysis & Applications》上回答了該問題。我們最近在不需要任何假定的前提下徹底回答了該公開問題。

[6]原創(chuàng)性地提出參數(shù)Lagrangian對偶方法，目前在0-1二次規(guī)劃問題和界約束二次規(guī)劃問題上有成功的應用。

[7]完美解決了等式約束S-lemma這一非凸二次優(yōu)化領域的基礎理論，論文被頂級期刊 《Mathematical Programming》錄用。

[8]解決了Pong和Wolkowicz 在2014《Computational Optimization and Applications》關于雙邊廣義信賴域子問題的強對偶成立充分條件的一個公開問題。至此，該問題的強對偶理論得以完全解決。
