We never rigorously de64257ned however what we meant by an algorithm or what it means for an algorithm to run in polynomial time This lack of a formal de64257nition doesnt matter much as long as we are coming up with descriptions of pr ocedures that. yahoocomqsNTTOdt brPage 6br 40 CGI CSC309 11 40 CGI CSC309 12 AUTHTYPE CONTENTLENGTH CONTENTTYPE GATEWAYINTERFACE PATHINFO PATHTRANSLATED QUERYSTRING REMOTEADDR REMOTEHOST REMOTEIDENT REMOTEUSER REQUESTMETHOD SCRIPTNAME SERVERNAME SERVERPORT SERVER They provide a precise formal de64257nition of what it means for a function to be computable Many other de64257nitions of computation have been proposed over the years for example one could try to formalize precisely what it means to run a program . NP-Complete. CSE 680. Prof. Roger Crawfis. Polynomial Time. Most (but not all) of the algorithms we have studied so far are easy, in that they can be solved in polynomial time, be it linear, quadratic, cubic, etc.. [Counter-tenor][Tenor][Tenor]Bass

Classifying problem complexity. Should have had all this in CS 252 – Quick review. Many problems have an exponential number of possibilities and we can try each option against some objective to get an answer. Note that this "testing" is fast (always polynomial!).
