jyotisi Posted June 10, 2011 Share Posted June 10, 2011 I'm in MSc IT and I'm doing project on timetable scheduling using genetic algorithm as my final year project. I have developed the code for it but the problem is timetable is not getting displayed. Please help.

xyph Posted June 10, 2011 Share Posted June 10, 2011 Haha what?! There are errors, and your build of PHP isn't displaying even fatal errors. error_reporting(-1); ini_set('display_errors', '1'); Quote Link to comment https://forums.phpfreaks.com/topic/238941-php-help/#findComment-1227808 Share on other sites More sharing options...
xylex Posted June 10, 2011 Share Posted June 10, 2011 What xyph said, and maybe start by sticking to writing PHP? $Rooms.remove($father); $Rooms.remove($mother); $child.extend($father[$Cpoint]); $child.extend($mother[$Cpoint]); $Rooms.append($child); Quote Link to comment https://forums.phpfreaks.com/topic/238941-php-help/#findComment-1227812 Share on other sites More sharing options...
jyotisi Posted June 10, 2011 Author Share Posted June 10, 2011 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 <?php //Declaration $TotalRooms=2;
