Grouping array positions by the method of k-means clustering

[dimon 32]

Creating an array of positions spiral manner fnc_spiral faced with the problem of how to group on the course.

Writing a script for their needs how would you solve your problem:

ffa_fnc_arrays_dist

Thanks ArseniyK, I did a function that splits the array into subarrays by the method of k-means clustering

I led them to a practical mind (i.e. they do work in MP mission) and a bit of optimizing standard techniques.

1. option

ffa_fnc_kmean_clustering

arrays= [12,arrays] call ffa_fnc_kmean_clustering;

weed out the empty submassive get

ffa_fnc_otsev= {
_cnt = _this select 1;
_array = [];
{
   if (typeName _x == "ARRAY" && {(count _x) > _cnt}) then
   {
       _array set [count _array,_x];
   };
} foreach (_this select 0);
};
arrays= [arrays,0] call ffa_fnc_otsev;

2. option (more is better)

ffa_fnc_kmean_clustering2
