Gasarch, William
William Ian gə-SARSH (/ɡəˈsɑːrʃ/-SARSH; [1] an haife shi a shekara ta 1959 [2]) Masanin kimiyyar kwamfuta ne Ba'amurke wanda aka sani da aikinsa a ka'idar hadaddun lissafi, ka'idar lissafi, ka'idar koyan kwamfuta, da ka'idar Ramsey. A halin yanzu shi malami ne a Sashen Kimiyyar Kwamfuta na Jami'ar Maryland tare da alƙawarin haɗin gwiwa a cikin Lissafi..
Gasarch mai ba da shawara ne akai-akai na ayyukan bincike na ɗaliban makarantar sakandare; ɗaya daga cikin waɗannan, tare da Jacob Lurie, ya lashe 1996 Westinghouse Science Talent Search for Lurie . [3] Ya yi rubutun ra'ayin kanka a yanar gizo tare da Lance Fortnow tun 2007. Ya kasance editan bita na ACM SIGACT NEWS daga 1997 zuwa 2015.

[gyara sashe | gyara masomin]Gasarch ya sami digirin digirgir a fannin kimiyyar kwamfuta daga Harvard a shekarar 1985, wanda Harry R. Lewis ya ba shi shawara. Kundin karatunsa an yi masa lakabi da Recursion-Theoretic Techniques in Complexity Theory and Combinatorics.[1] An dauke shi aiki a matsayin farfesa a jami'ar Maryland a cikin Fall of 1985. An kara masa girma zuwa abokin farfesa tare da aiki a 1991, kuma zuwa cikakken farfesa a 1998.[4]
Gasarch ya kafa (tare da Richard Beigel) filin Bounded Queries in Recursion Theory kuma ya rubuta takardu da yawa a yankin da wani littafi ya rufe shi a kan batun da aka rubuta tare da Georgia Martin, mai taken Bounded queries in Recoursion Theory . Ya wallafa littattafai irin su Matsala tare da Ma'ana, littafi mai cikakken ra'ayi game da lissafi da kimiyyar kwamfuta wanda ya hada da Clyde Kruskal kuma ya hada da ayyukan wasu furofesoshi kamar David Eppstein. Ya kuma kafa wani bangare na sake dawowa-ka'idar da ake kira Learning via Queries tare da Carl Smith . Kwanan nan ya fi shiga cikin combinatorics, musamman Ramsey Theory . [5] Ya rubuta bincike uku game da abin da masu tunani ke tunani game da matsalar P da NP: a cikin 2002, 2012, da 2019. [6][7][8] A cikin 2020 ya rubuta Mathematical Muffin Morsels: Babu wanda ke son karamin yanki tare da Erik Metz, Jacob Prinz, da Daniel Smolyak .
Lance Fortnow ya fara rubuta shafin yanar gizo kan kimiyyar kwamfuta ta ka'idoji tare da jaddada ka'idar rikitarwa a shekara ta 2002. Gasarch ya kasance mai baƙon yanar gizo har zuwa 2007 lokacin da ya zama mai ba da yanar gizo.
