Where… Re: What is the best way to store some distinct string? 14 Years Ago by kudresov If you do not have many strings, array of string should work. Normally you shouldn't worry about python efficency it has quite good code optimisation and python is not c it is not made for speed, so I would keep it simple and use something like array of strings.

Simple enough. Here's the code: [CODE] GLfloat alpha; BOOL Press[256]; GLuint GUIselect; BOOL objectInfo; BOOL scene; [/CODE] In … Radix Sort Efficency Help? 12 Years Ago by butler273 So, I'm back once again. This week I'm having issues with efficiency in a Radix Sort Algorithm. From what I understand this is the foundation of this algorithm. What operations might be costing me? For the basics I suppose I do understand push_ back being costly having to copy the entire array.

In the case of a Quicksort/Insertion sort hybrid, you could look in Google for some other folk's source code, or if you have VC++, you can look at the source code for their 'qsort()' function. It is not recursive and therefore a bit … Re: Quicksort/Insertion sort Hyrbid? 19 Years Ago by Jpowers22 void quickSort(int numbers[], int array_size) { q_sort(numbers, 0, array_size - 1); } void q_sort(int numbers[], int left, int right) { int pivot, l_hold, r_hold; l_hold = left; r_hold = right; pivot = numbers[left]; while (left < right) { while ((numbers[right] >= pivot) && (left < right))… Re: Quicksort/Insertion sort Hyrbid? 19 Years Ago by Chainsaw Assuming you have an insertion sort routine, try this modification to your code: [code] void q_sort(int numbers[], int left, int right) { int pivot, l_hold, r_hold; // If there are few records left to look at, use an insertion sort // because it is faster. if ((right - left) < INSERTION_SORT_THRESHOLD) {… Re: Quicksort/Insertion sort Hyrbid? 19 Years Ago by Narue >I can't get anything to work on the hybrid version. Can anyone help, provide tips or pointers? Oddly enough, I posted the full implementation for an optimized quicksort in the code snippets on this site. One of the optimizations is terminating recursion on small subfiles and then calling insertion sort on the "almost" sorted file. An… Re: Quicksort/Insertion sort Hyrbid? 19 Years Ago by subtronic One interesting way to figure out optimizations is through experimentation. You can time each pass for each implementation, record results and then plot them side by side on a graph. You can make adjustments accordingly to the insertion sort version's threshold to see if there's improvements.
