Conflict when use huge data timetable

[DucBeNho]

Hi.
I made a large data timetable for testing. Each time click generate button, time to solve a timetable are not a same. Sometime 5 sec, sometime 30 sec, some time it was loading forever, but same data.

Thanks a lot. Have a good day!

Hello!

Please, may I have your data file?

timetable

My timetable is little bit difficult to review. Because I use ID numbers instead of names.

Thank you for your file! I consider this behavior normal; the FET algorithm is semi-randomized, and a typical solution for your file breaks ~90 soft constraints.
