3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Complexity \Com*plex"i*ty\, n.; pl {Complexities}. [Cf. F. complexit['e].] 1. The state of being complex; intricacy; entanglement. The objects of society are of the greatest possible complexity. --Burke. 2. That which is complex; intricacy; complication. Many-corridored complexities Of Arthur's palace. --Tennyson. From WordNet r 1.6 [wn]: complexity n : the quality of being intricate and compounded; "he enjoyed the complexity of modern computers" [syn: {complexness}] [ant: {simplicity}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: complexityThe level in difficulty in solving mathematically posed problems as measured by the time, number of steps or arithmetic operations, or memory space required (called time complexity, computational complexity, and space complexity, respectively). The interesting aspect is usually how complexity scales with the size of the input (the "{scalability}"), where the size of the input is described by some number N. Thus an {algorithm} may have computational complexity O(N^2) (of the order of the square of the size of the input), in which case if the input doubles in size, the computation will take four times as many steps. The ideal is a constant time algorithm (O(1)) or failing that O(N). See also {NP-complete}. (1994-10-20)
