Linear Programming Thematic Tutorial

[ncohen]

Here it is ! The long-promised tutorial for LP. It is a translation of the french sagebook, and I hope I will be able to keep the two coordinated :-)

This patchremoved the old tutorial from the "constructions" document where it shouldn't have been put in the first place, and creates a new file in thematic_tutorials. It is up-to-date for the moment, though I hope to be able to work on some improvements with the CPLEX interface soon. It may only change te way CPLEX has to be installed, which would only require a minor edit later.

Apply:

1. trac_9836.patch​
2. trac_9836-reviewer.patch​
3. trac_9836 - renaming a variable.patch​
4. trac_9836-manifest.patch​

The two pictures should be added to the thematic_tutotials/ folder. This patch does not pass doctests for two reasons :

• Sage forgets the definition of the variables between different code sections (if you have any idea about how to fix this ^^;)

• There is a random doctest which should fail every second run, but it is a bit hard to fix with all the previous errors

Sorry to send this patch like that. This may be the last time I can access internet before next week (and I incidentally skipped my second meal today to finish it :-D), so if somebody knows how to fix these.. Otherwise, I'll take care of it when I'm back :-)

Updated thanks to wise advice :-)

It is now ready for review !

I'm happy with ncohen's tutorial. I have attached a reviewer patch to make it slightly better. Changes include:

• Directly add the two images with hg add. This makes sure that the images are under revision control.
• Where possible, cut off lines at about 75 characters.
• Some consistency in how you space headings.
• Some consistency in how you present Sage code.
• Use 4 space indentation.
• Numerous typo fixes.
• Simplify some of the prose to suit a tutorial format.

I need another pair of eyes to check my patch.

Thank you for your patch Minh ! I noticed reviewing it that I had forgotten to rename a variable, "poids", which means "weight" in french :-D

Could you check this small patch before changing this ticket's status ?

Thanks !

Good! Let's get it into the standard documentation.

I've attached a patch that fixes two Sphinx warnings:
