Constraint weights and dependency query

[Daniel]

Hey All,

I have the following FET file, the file solves just fine as is and in a reasonable time, under 10 min for most runs.

How ever when I set

Code Select Expand

Time constraint
All teachers must respect the maximum number of hours continuously
Weight (percentage)=90% (was 80% before)
Maximum hours continuously=2

the timetable no longer solves even after running it for a long time (5 hours was the longest try)

Is this to be expected, do I get it to some dependency issue with other constraints ?
The goal is to reduce the number of teachers with 3 lessons in a row to the minimum

Thanks,

Daniel

Unfortunately, this is expected.

You could try 85%, then 82.5% or 87.5%, and so on.
