;;This Sudoku-V1 - Draw a grid
;;This Sudoku-V2 - this creates 3 types of ants, and sets ant motion
;;This Sudoku-V3 - this sets up the initial data variables
;;This Sudoku-V4 - This fixes sant to stay in box.Also works for hant to change value in square.
;;This Sudoku-V5 - has hant amd vant working perfect
;;This Sudoku-V6 - has sant,hant,vant working perfect
;;This Sudoku-V7 - has a trial sudoku puzzel. Works to check if square can be a single number. :-)
;;This Sudoku-V8.1 - makes new ants called lone ants HLANT to check if a turf has 1 instance of a digit.
;;This Sudoku-V9 - THIS SOLVES PUZZLE
;;This Sudoku-V10 - with choise of puzzle...Final...Works perfect
;;This Sudoku-V13 - is v10 with SR and text
;;This Sudoku-V14 - Adds vlants works on easy, challenging, hard
;;This Sudoku-V15 - Adds suicide puzzle adds color coding of answers
;;This Sudoku-V16 - Make HLANT and hant the same ant
;;This Sudoku-V17 - Make vLANT and vant the same ant
;;This Sudoku-V18 - Use easy loops for making the initial grid
;;This Sudoku-V19 - 

;; make the three types of ant movements done by a single ant
;; so far this only check which numbers CAN be in a box. Needs to also check which numbers are unique to a rcs.

## WHAT IS IT?

This is an ant based Sudoku puzzle solver

## HOW IT WORKS

There are 36 ants created out of 4 breeds. The breeds are:  
hants : These ants go across a row and change the list of possible values in every blank square, depending on the permanent values of the other squares in the row. They also will make permanent a value if there is only one possible value for that square. They leave an updated list in that square. Like a "pheromone". 

vants : These ants go down a column and change the list of possible values in every blank square, depending on the permanent values of the other squares in the column. They leave an updated list in that square. Like a "pheromone". 

sants : These ants go back and forth in a block and change the list of possible values in every blank square, depending on the permanent values of the other squares in the block. They leave an updated list in that square. Like a "pheromone". 

hlants : These ants go across a row and remember a list of possible values in every blank square. They add up the possible values. At the end of the row if there are any values equal to 1, then there is only one possibility of that number in that row. It will make that square permanently that number next time it lands on it. 

## HOW TO USE IT

There are 3 different puzzles you may choose. These are randomly chosen out of a Sudoku puzzle book. One is easy, one is challenging, and one is hard.  
You can vary the speed with the slider at the top. This would allow you to see the ants as they move.

## THINGS TO NOTICE

Because the way the ants operate, by leaving a "smell" of all possible values, they can do much more complex auditing than a human can. So some times a hard puzzle is quicker to solve than an easy one.  
The ants don't stop when the puzzle is finished. Each ant does not know what the goal of the entire ant colony is.

## EXTENDING THE MODEL

I would like to do a 16x16 puzzle next. It would require no change in the algorithms.  
Since each square can not have any permanent value that is also in that row, column, or block, there are 20 other squares that are influenced by any single square. These 20 squares are called a unit. One ant per unit would be very fast and efficient, and only require one breed of ants for the whole puzzle.


## CREDITS AND REFERENCES

This code was written by Kgwedi Wise. There were many helpful sites on the web that helped clarify some of the programming and algorithms.
