個人情況簡介:
佘志坤,男,1977年出生。北京航空航天大學數(shù)學與系統(tǒng)科學學院教授、博士生導師。2007年度北京市優(yōu)秀人才,2007年度北京航空航天大學藍天新秀,2008年度北京市科技新星,2013年度教育部新世紀優(yōu)秀人才,2014年度國家優(yōu)秀青年科學基金項目獲得者。獲2013年度教育部自然科學獎一等獎(第三完成人)。1995年9月到2005年6月,就讀于北京大學數(shù)學科學學院,獲理學學士和博士學位(碩博連讀);2004年1月到2006年12月,工作于德國馬普計算機科學研究所。
他主要在混成系統(tǒng)自動驗證、微分方程和動力系統(tǒng)、符號-數(shù)值計算、計算復雜性、空間非開普勒軌道分析與優(yōu)化控制等領域從事基礎和應用研究。博士期間,在導師鄭志明教授的指導下,提出了偽除機理論,從而推廣了Smale等提出的著名的BSS機器(即所謂的實圖靈機模型),并在2002年國際數(shù)學家大會分會場做此研究成果的報告。以此為基礎,在實代數(shù)系統(tǒng)的研究上也取得了一系列原創(chuàng)成果。Herbrand獎得主、德國馬普計算機科學研究所前所長H.Ganzinger教授高度重視,特意邀請他前往德國馬普計算機科學研究所做短期訪問;隨后,在未取得博士學位情況下,他被破格邀請到馬普從事博士后研究,并進入德國大型跨區(qū)域科研項目AVACS(www.avacs.org)的核心研究小組之中。
在混成系統(tǒng)自動驗證領域,他對非線性混成系統(tǒng)安全性自動驗證問題進行了直接處理,突破了之前理論主要通過線性近似來討論的局限性,并開發(fā)了自動驗證軟件Hsolver(hsolver.sourceforge.net/)。由美國工程院院士Alberto L. Sangiovanni-Vincentelli發(fā)表的、詳細介紹國際上混成系統(tǒng)研究方面最新進展的綜述性學術論文《Languages and Tools for Hybrid Systems Design》(Foundations and Trends in Electronic Design Automation. Vol. 1, No 1/2 (2006), 1-193)在134至140頁介紹的就是其工作,其評價是“HSolver improves the traditional method by implementing a pruning algorithm that removes uninteresting parts of the state space before reducing the grid size. Consequently, the refinement of the over-approximation can be obtained even without increasing the number of grid locations, one of the causes of exponential blowout in the verification algorithms for hybrid systems”、“The language for describing hybrid systems is very easy to understand. There are no limitations in describing a single automaton and the limited number of statements in the language makes it simple to use”。
歸國后,他把混雜(成)系統(tǒng)引入到空間非開普勒軌道的分析與優(yōu)化控制之中,被譽為“從混雜系統(tǒng)研究空間軌道構思新穎,是航天器軌道研究的一個新方向”。 發(fā)表在《宇航學報》的學術論文《空間非開普勒軌道分析與控制中的數(shù)學問題》被西北工業(yè)大學精品課程《航天器飛行力學》列為學科前沿(http://jpkc.nwpu.edu.cn/jp2011/04/xuekeqianyan.html)。
他獨立撰寫國防報告3部,在ACM Transactions on Embedded Computing Systems、SIAM Journal on Control and Optimization、Journal of Symbolic Computation、Celestial Mechanics and Dynamical Astronomy等領域國際頂級刊物和AAAI、CAV、ISSAC、HSCC等領域國際頂級會議上發(fā)表學術論文40余篇。研究成果被來自于Massachusetts Institute of Technology、Stanford University、University of California at Berkeley、University of Cambridge、University of Oxford、ETH Zurich、Carnegie Mellon University、RWTH Aachen、日本早稻田大學、新加坡國立大學、清華大學、CNRS、INRIA、MPII、中國科學院軟件所等國內外著名機構的學者他引300余次,單篇最高他引90余次。特別地,圖靈獎得主Edmund M. Clarke、美國工程院院士Alberto L. Sangiovanni-Vincentelli、美國工程院院士、歐洲科學院院士Moshe Y. Vardi、歐洲科學院院士Marta Kwiatkowska、清華大學孫家廣院士、斯坦福大學Prof. Zohre Manna、ACM會士、IEEE會士Prof. John A. Stankovic、ACM會士Prof. Lawrence Paulson、IEEE會士Prof. Bruce Krogh、IEEE會士Prof. Bud Mishra、IEEE會士Prof. Insup Lee、IEEE會士Prof. John Lygeros、IEEE會士Prof. George Pappas等給予了積極的正面評價,諸如“明顯優(yōu)勢”、“極大改進”、“靈感之源”等等。
