Difference constraints

#41 henriean closed 1 year ago
0
Write script for testing if and when Bellman-Ford with rounding stops statistically.

#40 henriean opened 2 years ago
0
Edit code on difference constraints to stop after 2n-1 iterations! (And to do this only when integer constraints.)

#39 henriean opened 2 years ago
0
Improvement: Easy-to-implement flow recognition and extra benchmarking/text about this.

#38 henriean opened 2 years ago
0
Write: Conclusion/discussion. Talk about possibilities with portofolio solvers and other types of recognizers.

#37 henriean opened 2 years ago
0
Write: Tidy up more. Add index and references, fix cross-references, fix possible todos.

#36 henriean opened 2 years ago
0
Write: Add examples of difference constraints problems, the use and result of the program, and a nice graph to go with it.

#35 henriean opened 2 years ago
0
Continue benchmarking. Add results of what I have at this time, and discuss in thesis.

#34 henriean opened 2 years ago
0
Write and code: Edit text on the difference constraints.

#33 henriean opened 2 years ago
0
Write: How I substituted equal_to variables, and the representation of the problem in general.

#32 henriean opened 2 years ago
0
Write: The choices regarding getting the data, and other possibilities about implementing solver interface.

#31 henriean opened 2 years ago
0
Write: About bridging.

#30 henriean opened 2 years ago

Pretty printing of solution. (Nice feature, but if too much to do, don't prioritize it.)

#29 henriean opened 2 years ago
0
Make representation of problem more flexible for an Algorithm, meaning they define their own Representation instead of using LPRep.

#28 henriean opened 2 years ago
0
Fix parallelization for recognize and optimize

#27 henriean opened 2 years ago
0
Interface

#26 henriean closed 2 years ago

Look at codebase and convert comments to docstrings.

#25 henriean opened 2 years ago

Switch from converting to matrices etc. into caching optimicer/direct mode/unsafe backend.

add some more generality to functions and add setup for own bellman-ford.

#21 henriean closed 2 years ago

Finish impementing results regarding difference constraints.

#20 henriean opened 2 years ago
0
Improvement: See if possible to implement the flow recognizion procedure, even though I haven't understood all concepts.

#19 henriean opened 2 years ago
0
Add theory about cuts or solvers or other stuff I researched and wrote notes about.

#18 henriean opened 2 years ago
0
Infrastructure + examples, so that the project is more like new functionality within jump. Write documentation/tutoral for how to make own plugin.

#17 henriean opened 2 years ago
0
Discussion about multiflex/portfoliosolver.

#16 henriean opened 2 years ago

Benchmarking. Make plan, and start tests.

#15 henriean opened 2 years ago
1
Make sparse matrix more elegant.

#14 henriean opened 2 years ago
1
Make sure sparce matrix is working.

#13 henriean opened 2 years ago
0
Document code.

#12 henriean opened 2 years ago
0
How to ask about and return regarding feasibility only.

#11 henriean opened 2 years ago
0
If problem does not fit LPModel, give feedback.

#10 henriean opened 2 years ago
0
Paralelity considering the different recognition procedures. Think more about memory vs resources etc.

#9 henriean opened 2 years ago
0
Write about the implememntation, and add examples in the thesis.

#8 henriean opened 2 years ago
0
Improvemen: Divide the problem into a part of difference constraints, so that one can rule out feasibility.

#7 henriean opened 2 years ago
0
Look at if there are "easy" cases with some x's above or below 0.

#6 henriean closed 2 years ago
0
Set up a working interface.

#5 henriean closed 2 years ago
0
Write about moving solutions for difference constraints if x>=0.

#4 henriean closed 2 years ago
