Select pairs of points uniformly at random, with replacement, and let be the minimum distance of the selected pairs. Round the input points to a square grid of points whose size (the separation between adjacent grid points) is d {\displaystyle d} , and use a hash table to collect together pairs of input points that round to the same grid point.
The following is a dynamic programming implementation (with Python 3) which uses a matrix to keep track of the optimal solutions to sub-problems, and returns the minimum number of coins, or "Infinity" if there is no way to make change with the coins given. A second matrix may be used to obtain the set of coins for the optimal solution.
In general, there may be many different stable matchings. For example, suppose there are three men (A,B,C) and three women (X,Y,Z) which have preferences of: A: YXZ B: ZYX C: XZY X: BAC Y: CBA Z: ACB. There are three stable solutions to this matching arrangement: men get their first choice and women their third - (AY, BZ, CX);
(If we only need the value m[n,W], we can modify the code so that the amount of memory required is O(W) which stores the recent two lines of the array "m".) However, if we take it a step or two further, we should know that the method will run in the time between O ( n W ) {\displaystyle O(nW)} and O ( 2 n ) {\displaystyle O(2^{n})} .
Otherwise, the algorithm enters Phase 2. A rotation in a stable table T is defined as a sequence (x 0, y 0), (x 1, y 1), ..., (x k-1, y k-1) such that the x i are distinct, y i is first on x i 's reduced list (or x i is last on y i 's reduced list) and y i+1 is second on x i 's reduced list, for i = 0, ..., k-1 where the indices are taken ...

An algorithm created independently by Chin [9] and Hu & Shing [10] runs in O(n) and produces a parenthesization which is at most 15.47% worse than the optimal choice. In most cases the algorithm yields the optimal solution or a solution which is only 1-2 percent worse than the optimal one. [5]
If the solution to any problem can be formulated recursively using the solution to its sub-problems, and if its sub-problems are overlapping, then one can easily memoize or store the solutions to the sub-problems in a table (often an array or hashtable in practice). Whenever we attempt to solve a new sub-problem, we first check the table to see ...
