O(N) is first order, O(N 2 ) is second, and so on<br />

maximum [173,0.1.1] or largest element of a totally ordered set<br />

find the maximum of a function with respect to variable x<br />

argument of operator or function, or variable of optimization<br />

supremum of totally ordered set X , least upper bound, may or may<br />

not belong to set [173,0.1.1]<br />

argument x at supremum of function f ; not necessarily unique or a<br />

member of function domain<br />

specifies constraints to an optimization problem<br />

minimum [173,0.1.1] or smallest element of a totally ordered set<br />

find the function minimum with respect to variable x<br />

infimum of totally ordered set X , greatest lower bound, may or may<br />

not belong to set [173,0.1.1]<br />

argument x at infimum of function f ; not necessarily unique or a<br />

member of function domain<br />
