University Course Timetabling coursett-1.3.jar execution #20

Closed ebracci closed 3 years ago

ebracci commented 3 years ago

Hi,

I was looking for run the solver without using the unitime web application using this page as example https://www.unitime.org/cpsolver_examples.php.

I am interested in University Course Timetabling but I have some questions.

1) Where I can find the coursett-1.3.jar? If I use the cp-solver.1.3.jar the execution returns this error:

Errore: impossibile inizializzare la classe principale org.cpsolver.coursett.Test
Causato da: java.lang.NoClassDefFoundError: org/apache/log4j/Layout

2) Is it possible to use the same jar to solve a CurriculaRequestsCourseDemands or CurriculaLastLikeCourseDemands problems? How can I do that?

Thank you for your attention.

The individual JARs (for each problem) are available if you download the CPSolver build from the nightly builds page, e.g., https://builds.unitime.org/cpsolver-1.3_bld238.zip. You can also use the cpsolver-all-1.3.jar. In both cases, you need to have log4j-1.2.17.jar and dom4j-2.1.3.jar in the same folder as the solver JAR.

The course timetabling problem XML already has individual student course demands listed, see Students section of the data format. Combining curricula with course requests or last-like course demands are done in UniTime, when the problem is loaded into the solver.
