地點(diǎn):第一教學(xué)樓1211室
報(bào)告題目:A Simple Proof of the 4-Color Theorem
報(bào)告人簡介: Wei-Chang Yeh為臺(tái)灣清華大學(xué)工業(yè)工程與工程管理系特聘教授,美國德州大學(xué)工業(yè)工程博士。 研究領(lǐng)域包括綠色供應(yīng)鏈、云端運(yùn)算和智能電網(wǎng)。已在國際知名期刊及國際會(huì)議發(fā)表論文250余篇。受邀擔(dān)任國際知名期刊 《IEEE可靠性匯刊》和《可靠性工程及系統(tǒng)安全》副主編。他提出了一種被稱作簡化群優(yōu)化 (SSO) 的新型軟件計(jì)算算法,該算法簡潔而高效地解決了NP-hard問題。獲得授權(quán)發(fā)明專利50項(xiàng)。由于Yeh教授在工業(yè)工程等領(lǐng)域的杰出貢獻(xiàn),被多個(gè)國際會(huì)議邀請做大會(huì)特邀報(bào)告 (Keynote Speaker) 。
內(nèi)容摘要:The four-color theorem states that no more than four colors are required to color all nodes in planar graphs such that no two adjacent nodes are of the same color. The theorem was first propounded by Francis Guthrie in 1852. Since, scholars have either failed to solve this theorem or required computer assistance to prove this theorem. Hence, the goal of this paper is to provide the first correct proof composed with the human brain and without computer assistance in 2 pages only for this 170 year-old mathematical problem.
