N-Queens

Solving N-Queens Problem Using Genetic Algorithm in Clojure

Usage

NOTE you may need to evaluate it multiple times to get the answer.

------- RUN METHOD --------

> lein run 8 200 0.3 0.03

> lein run 
Wrong Input arguments!
USAGE : 'Number of Queens' 'Number of Chromosomes' 'Crossover-Rate[0.0-1.0]' 'Mutation Rate[0.02-0.1]'

------- DEBUG METHOD 1-------

> lein repl
> (load "core")
> (-main "8" "200" "0.3" "0.03")

------- DEBUG METHOD 2-------

1. open "core.clj" in emacs
2. run cider (C-c M-j)
3. evaluate buffer (C-c C-k)
4. (-main "8" "200" "0.3" "0.03")

--------- SAMPLE RESULTS ------------------

TIMEOUT! fitness value= 55/2 population= 5000 =>"Elapsed time: 24605.194236 msecs"

GOT IT! at 12 th iteration: [[3 5] [2 7] [4 2] [5 6] [6 1] [1 0] [7 3] [0 4]] population= 5000 =>"Elapsed time: 14089.947256 msecs"
