Custom FET for Moroccan schools

[Liviu Lalescu]

I did that on the official Morocco example, seems to work (see attached archive). Constraints introduction took about 15 minutes. This is the good news.

The bad new is that it is slower than it should be. One reason is that the data is more difficult. But another reason is that the occupy constraint is not as efficient in this case as a modified max hours for real day.

Seems ~4 times slower with the new constraint. I don't know how much is because the data is more difficult and how much because of inefficiency.

But anyway file is solved.

Should I add this file as an official example, in Morocco?

[Liviu Lalescu]

It is a good thing that I considered this problem. Because I found out that the new constraints slow down much the generation, and I dag into the problem. The code was good, but I found an improvement, and now the speed is comparable with the speed without the new constraints.

Without improvement, speed was, for the file attached in the previous post, 3 m 57 s, and now it is 1 m 35 s. So, more than twice the speed now.

I released a new snapshot. See snapshots section here on forum.

[Chafik Graiguer]

I agree
The new constraint made generation much slower.
Now I will test the new snapshot

[Liviu Lalescu]

alfaromeo, since the constraint is working, I would like to:

1) Add the new file with the new constraints to the official Morocco samples.

2) Update Morocco instructions in the official FET examples directory: Arabic and English ones.

Could you help, please?

I intend to release the new version in maybe less than a week; if you cannot do these I will try to do them myself.

Did you already have any sentences in english?

[Chafik Graiguer]

Here is the Arabic instructions

Something like:

"
To ensure that the students will have maximum 7 hours in a real day (morning and afternoon), you have to use the constraint a set of activities occupies max time slots from selection.

You need to add number_of_real_days constraints for each students set. Add all activities of a students set, then select all the 8 slots of the first real day, and choose the max number of occupied slots to be 7. This is one constraint. Then, add similar constraints for each remaining real day. Then, continue with the next students set.

Further details are left to the user (like the case in which you are using complex students sectioning into sets).
"

[Chafik Graiguer]

Well
I added nearly the same thing in Arabic, but more in details

[Liviu Lalescu]

If you consider I should detail some more, tell me your words in English.

[Chafik Graiguer]

Well

Chafik, please translate these two things for me:

"
Note: If you are using advanced students sectioning, you may need to adapt steps 5 to 7 to your situation.
"

Also, I want to insert this:

"
The document was updated on 17 October 2011, to add new information about students max 7 hours per real day.
"

into Arabic, where exactly?

[Chafik Graiguer]

I update both Arabic and English readme, including your words
Attached

[Liviu Lalescu]

You forgot to update the Arabic document (to add my two phrases about document modification date and advanced students sectioning). Also, about the strings "VERY IMPORTANT" and "UPDATE" in English, I want to remove them.

[Chafik Graiguer]

You can remove UPDATE from English document
I sent the wrong file,
the good one is attached

[Liviu Lalescu]

Thank you! Done!
