Hello, MTD, you wrote: S>> And the Whip - it is not clear. MTD> thus that the Whip did not consider, as algorithms are fulfilled on the modern iron, such theory in vacuum. The nobility it is necessary, but each time it would be necessary to think, and blindly to trust in the Island I each time told "it is necessary to measure", instead of to "think"." To think "it it is necessary, but not this key. And" on the modern iron "it is specificity not only the Whip. I now looked at Kormena, Siena, Sedzhvika - is not mentioned anywhere - at least was not present either in a table of contents, or in the index. Therefore it is necessary to suppose that to them in pair mandatory to read" Computer achitecture: a quantitative approach "or analog. Still you for some reason spread stray logical communication" algorithms, complexity-> the Whip ". A whip - the base and historical basis, but now it to use as the absolute already rather late. S>> He does not state the reverse. MTD> for an estimation of speed of algorithms it is offered to use it is not always true. For example, at a binary tree and the arranged array the search asymptotics is identical - a logarithm. Whether it means, what they are equally effective? No, after all the tree can be spread on storage because of it there will be constant misses in and the arranged array appears in times more effectively. It is considered at the Whip? No, here about that and speech. The real world should be considered always. Somewhere the algorithm in 100 times faster on RAM, but in 2 times is more gluttonous on memory size will be braked because of a swap. Somewhere very effective it becomes normal sorting suddenly more slowly a vial of that comparing in 1000 times is more expensive than an exchange. You reading to the Whip for some reason look only at outputs, instead of to the analysis carried out by it. And after all to what it learns is to analyze from bases. And at all thus do not know anybody, except the Whip... Simply frighten of it.
