The reason is that the logical formulas generated have exponential-size proofs in the proof system used by DPLL(T) SMT-solvers, thus all current stable SMT-solvers; thus this approach is intractable. In this talk we explain how to work wound this difficulty by adding<br \/>\nsupplementary, redundant constraints (&#8220;cuts&#8221;) to the formula, in order to kill its complexity.                                                         <\/p>\n<p>Joint work with Julien Henry, Claire Maiza, Diego Caminha\n<\/p><\/blockquote>\n<p><!--Ne pas oublier les tags (mots-clefs, en bas \u00e0 droite et de bien mettre un nom correct dans le permalink en haut--><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Death by a thousand cuts (worst-case execution time by bounded model checking) !!! report\u00e9 au : Friday, 29 nov 2013, LIP, 13H30, Salle du Conseil David Monniaux, Verimag R\u00e9sum\u00e9: In order to bound the worst case execution time of loop-free &hellip; <a href=\"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/monniaux-wcet\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[13,38,37,36,64],"class_list":["post-144","post","type-post","status-publish","format-standard","hentry","category-wg","tag-compsys","tag-monniaux","tag-smt","tag-wcet","tag-wg"],"_links":{"self":[{"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/posts\/144","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/comments?post=144"}],"version-history":[{"count":5,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/posts\/144\/revisions"}],"predecessor-version":[{"id":168,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/posts\/144\/revisions\/168"}],"wp:attachment":[{"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/media?parent=144"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/categories?post=144"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ens-lyon.fr\/LIP\/COMPSYS\/wp-json\/wp\/v2\/tags?post=144"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
