PHP algorithm which calculates all possible combinations of dividing one set between another set

I'm looking for a kind of 2-dimensional combination algorithm .. if that's the correct wording. I'm pretty experienced with PHP, but not with algorithms and advanced math so bear with me please. I have a set of elements that I want to combine with another set of elements and calculate all possible combinations so that I can analyze it af...

Greedy algorithm and coin algorithm?

I've been working on some problems/exercises on Project Euler hoping to practice/learn some optimal algorithms and programming idioms with python. I came across the this problem Euler #76 which is asking to find all the unique combinations using at least two values to sum to 100. In researching this problem I came across people referring...

Is there a specific algorithm for generating all combinations of n elements, taken n-1 at a Time

I know of the algorithm for the general case (e.g. generating all combination of n elements taken m at a time) but I was wondering if there was a faster one specifically designed for the case m=n-1. Also, if such an algorithm exists, could anyone point to a C/C++ implementation?...

Add item to array in VBScript

How do you add an item to an existing array in VBScript? Is there a VBScript equivalent to the push function in Javascript? myArray has three items, "Apples", "Oranges", and "Bananas" and I want to add "Watermelons" to the end of the array.

Path finding algorithm difficulty

Problem: Modify the A* algorithm we optimized for fewer turns. The algorithm will now find a path from (a,b) to ANY TILE ADJACENT TO (x,y), where (x+1,y) or (x-1,y) are favored when possible. My attempted solution: Run the original A* algorithm from (a,b) to (x,y). Find the last coordinate in the path that travels through (x-1, ) or (x+...

Algorithm For Bin packing with different size of bins and object

I need an algorithm that optimize the use of steel in planning, using bin packing.

For example, if we wanted to find the set_union of the following lists: L1 L2 hi goodbye by...

Pyramid Lucas-Kanade algorithm with Java

I have a question about Lucas-Kanade optical-flow algorithm. I understood that "Pyramid" Lucas-Kanade algorithm is more better than simple Lucas-Kanade algorithm. So I made its program with Java because I can't use OpenCV's program. But the program doesn't work well. So please teach me the program of "Pyramid" Lucas-Kanade algorithm, or t...

Horspool algorithm for multiple occurrences of the same pattern

Evenly distributing n points on a sphere

I find myself overwhelmed with information, and I still haven't been able to find exactly what I'm looking for, at least not in a format I can convert for my uses.

ray casting algorithm without side coordinates

Im trying to define if a point is inside a polygon. Only the coordinates of the corners are given. After some research I found the Ray casting algorithm but it looks like i need a vector filled with the coordinates of the polygons side. I tried to calculate these coordinates as well, but it doesn't look like this is the solution. Maybe I...

Optimization When Objective Function Can Only Be Approximately Computed

I have some graph algorithms that depend on a moderate number of parameters (say 2-6), and which don't always succeed in finding what they want (they want `good enough' solutions to problems known to be hard, like mincut/maxflow). I also have a very large family of graphs that I'd like to use the algorithms on. My current goal is to find...

Does nodejs have a working diff library or algorithm?

Efficient Multiplication of Varying-Length #s [Conceptual]

So it seems I "underestimated" what varying length numbers meant. I didn't even think about situations where the operands are 100 digits long. In that case, my proposed algorithm is definitely not efficient. I'd probably need an implementation who's complexity depends on the # of digits in each operands as opposed to its numerical value,...

Mind the gap! The perils of falling for a cougar leave you 'poorer, uglier, and less intelligent'

A study from the University of Colorado has found that couples with big age gaps are more likely to be 'poorer, uglier, and less intelligent' than couples who are closer in age.

Genetic algorithm crossover

I have a question regarding genetic algorithm so: Should crossover be carried out differently, e.g. only at “gene” boundaries. Should representations include “noise” to improve performance – or does it make it worse? I have search about noise improve the performance of crossover and i cant find anything someone please help! Thank you.
