std::setis an associative container that contains a sorted set of unique objects of typeKey. Sorting is done using the key comparison functionCompare. Search, removal, and insertion operations have logarithmic complexity. Sets are usually implemented asRed–black trees. ...

time complexity of *all* container access operations. [1] In my case (gcc 4.1.1) I can't swear that the time complexity of size() for std::set is not documented... but if it is it's certainly well hidden away. [...] Best regards, -- Lionel B Kai-Uwe Bux #13 Feb 2 '07...
When we need to read a specified bit, we can use theANDbit operator to perform operations between the original bit string and 0000...1...0, then shift the obtained value to the right and the bit to the right The number is defined by the index of the number of digits read. The Boo...
22 Hence syntax (or whatever formal operations it reflects) seems to be causally involved in the genesis of these denotations. This suggests the conclusion that as the derivation unfolds (structural complexity builds up), semantic complexity builds up; but syntactic complexity engenders the asymmetric...

In order to acquire the lock, the client performs the following operations: It gets the current time in milliseconds. It tries to acquire the lock in all the N instances sequentially, using the same key name and random value in all the instances. During step 2, when setting the lock in ...

It depends on the order in which the operations are done/scheduled, and because (a+b)+c is generally different from a+(b+c), it would add some complexity to have pure determinism. The difference should also be very small, and not affect general accuracy. Is there a reason why you ...
The crossover and mutation operations of the genetic algorithm are also improved. Since the initial population distribution obtained by GPSA is more uniform than that obtained by the random algorithm, a better solution can often be acquired in the evolutionary operation. The main contributions of ...
