We know that the basic technique of quicksort illustrated above uses recursion for sorting the array. In the recursive quicksort after partitioning the array, the quicksort routine is called recursively to sort the sub-arrays. The below Implementation demonstrates the quicksort technique using recursi...
To avoid run-away recursion fluxsort switches to quadsort for both partitions if one partition is less than 1/16th the size of the other partition. On a distribution of random unique values the observed chance of a false positive is 1 in 3,000 for the quasimedian of 9 and less than 1...

in a worst case scenario, even though the (much more common) random case only recurses 2.4 times the baseline. Nevertheless, Log2(N) performance is achieved. Applications that need to sort more than a hundred million elements should limit the recursion depth by using the 87.5% sweet spot, ...
1)quick sort快速排序 1.Using the idea of quick sort for reference and based on the analyses of interharmonic specialties,this algorithm gets a linearity sequence that the harmonics and interharmonics components have been sorted,and ascertains the dominant harmonics and interharmonics components by th...
The quick select algorithm can get the top K element from a list of N items in linear time, O(n), with a very reasonable multiplication factor. The quick select does not use recursion so the performance is great for even large datasets....

Callbacks, Recursion At left, the sender sends an asynchronous message to the active-object receiver for background processing, passing it the object to notify when the operation is complete (in this case, itself). The receiver calls it's own msg(...) method to process the request, and ...
