this is the action.php file in which genetic algorithm is there which should generate the timetable but this code only generates days and subjects in the timetable is not generated.I have also attached the html file first run the tableform.htm and give inputs as no of hours of lecture:6,max lecture per week:8,max lec per day:3 and num of generation:2
