It also has an interior point solver for LP written by Lukas Schork, an active set solver for QP written by Michael Feldmeier, and a MIP solver written by Leona Gottwald.

-HiGHS is a high performance serial and parallel solver for large scale sparse -linear optimization problems of the form - -$$ \min \quad \dfrac{1}{2}x^TQx + c^Tx \qquad \textrm{s.t.}~ \quad L \leq Ax \leq U; \quad l \leq x \leq u $$ - -where Q must be positive semi-definite and, if Q is zero, there may be a requirement that some of the variables take integer values. Thus HiGHS can solve linear programming (LP) problems, convex quadratic programming (QP) problems, and mixed integer programming (MIP) problems. It is mainly written in C++, but also has some C. It has been developed and tested on various Linux, MacOS and Windows installations. No third-party dependencies are required. - -HiGHS has primal and dual revised simplex solvers, originally written by Qi Huangfu and further developed by Julian Hall. It also has an interior point solver for LP written by Lukas Schork, an active set solver for QP written by Michael Feldmeier, and a MIP solver written by Leona Gottwald. Other features have been added by Julian Hall and Ivet Galabova, who manages the software engineering of HiGHS and interfaces to C, C#, FORTRAN, Julia and Python. - -Find out more about HiGHS at https://www.highs.dev. -

Since `PDHG_PostSolve` converts the solution to the problem solved by cuPDLP-c into a solution for the original problem, "un-permuting" `y` according to the reording of the constraints, it should negate the duals for pure upper-bounded constraints. - ## Problem with sys/time.h The HiGHS branch add-pdlp compiles and runs fine on @jajhall's Linux machine, but CI tests on GitHub fail utterly due to `sys/time.h` not being found. Since HiGHS won't be using the cuPDLP-c timing, this can be commented out using a compiler directive. ## Handling infeasible or unbounded problems -cuPDLP-c fails to terminate with the infeasible and unbounded LPs in unit tests `pdlp-infeasible-lp` and `pdlp-unbounded-lp` in `highs/check/TestPdlp.cpp`. In both cases the primal and dual step sizes grow steadily - eventually heading to infinity. Presumably, once they have reached a tolerance, cuPDLP-c should terminate so that infeasibility and unboundedness can be deduced according to whether the current iterate is primal feasible (as it is for `pdlp-unbounded-lp`). +cuPDLP-c now terminates with status `INFEASIBLE_OR_UNBOUNDED` for the infeasible and unbounded LPs in unit tests `pdlp-infeasible-lp` and `pdlp-unbounded-lp` in `highs/check/TestPdlp.cpp`. In the case of the unbounded LP, PDLP identifies a primal feasible point, so unboundedness can be deduced. This is done in `HighsSolve.cpp:131. ## To be done -- Remove cuPDLP-c timing using a compiler directive - Make cuPDLP-c less chatty -- Create HiGHS options to feed cuPDLP-c - Return iteration count etc from cuPDLP-c From 2df50399c5123eaf8b350a423e1cd2d96ef5d3e8 Mon Sep 17 00:00:00 2001 From: JAJHall Date: Tue, 6 Feb 2024 01:02:17 +0000 Subject: [PATCH 294/497] Returning iteration count from cuPDLP-c --- highspy/highs_bindings.cpp | 3 +++ src/interfaces/highs_csharp_api.cs | 5 +++-- src/lp_data/Highs.cpp | 4 ++++ src/lp_data/HighsCallback.cpp | 1 + src/lp_data/HighsCallbackStruct.h | 1 + src/lp_data/HighsInfo.cpp | 1 + src/lp_data/HighsInfo.h | 6 ++++++ src/lp_data/HighsInterface.cpp | 1 + src/pdlp/CupdlpWrapper.cpp | 7 ++++--- src/pdlp/cupdlp/README.md | 5 ++++- src/pdlp/cupdlp/cupdlp_solver.c | 3 ++- src/pdlp/cupdlp/cupdlp_solver.h | 2 +- 12 files changed, 31 insertions(+), 8 deletions(-) diff --git a/highspy/highs_bindings.cpp b/highspy/highs_bindings.cpp index 685ac6e363..859cc95d25 100644 --- a/highspy/highs_bindings.cpp +++ b/highspy/highs_bindings.cpp @@ -694,6 +694,7 @@ PYBIND11_MODULE(_highs, m) { .def_readwrite("qp_iteration_count", &HighsInfo::qp_iteration_count) .def_readwrite("crossover_iteration_count", &HighsInfo::crossover_iteration_count) + .def_readwrite("pdlp_iteration_count", &HighsInfo::pdlp_iteration_count) .def_readwrite("primal_solution_status", &HighsInfo::primal_solution_status) .def_readwrite("dual_solution_status", &HighsInfo::dual_solution_status) @@ -1139,6 +1140,8 @@ PYBIND11_MODULE(_highs, m) { &HighsCallbackDataOut::simplex_iteration_count) .def_readwrite("ipm_iteration_count", &HighsCallbackDataOut::ipm_iteration_count) + .def_readwrite("pdlp_iteration_count", + &HighsCallbackDataOut::pdlp_iteration_count) .def_readwrite("objective_function_value", &HighsCallbackDataOut::objective_function_value) .def_readwrite("mip_node_count", &HighsCallbackDataOut::mip_node_count) diff --git a/src/interfaces/highs_csharp_api.cs b/src/interfaces/highs_csharp_api.cs index c566756971..74ebd564e7 100644 --- a/src/interfaces/highs_csharp_api.cs +++ b/src/interfaces/highs_csharp_api.cs @@ -909,8 +909,9 @@ public SolutionInfo getInfo() DualBound = this.GetValueOrFallback(HighsLpSolver.Highs_getDoubleInfoValue, "mip_dual_bound", double.NaN), ObjectiveValue = this.GetValueOrFallback(HighsLpSolver.Highs_getDoubleInfoValue, "objective_function_value", double.NaN), NodeCount = this.GetValueOrFallback(HighsLpSolver.Highs_getInt64InfoValue, "mip_node_count", 0l), - IpmIterationCount = this.GetValueOrFallback(HighsLpSolver.Highs_getIntInfoValue, "simplex_iteration_count", 0), - SimplexIterationCount = this.GetValueOrFallback(HighsLpSolver.Highs_getIntInfoValue, "ipm_iteration_count", 0), + IpmIterationCount = this.GetValueOrFallback(HighsLpSolver.Highs_getIntInfoValue, "ipm_iteration_count", 0), + SimplexIterationCount = this.GetValueOrFallback(HighsLpSolver.Highs_getIntInfoValue, "simplex_iteration_count", 0), + PdlpIterationCount = this.GetValueOrFallback(HighsLpSolver.Highs_getIntInfoValue, "pdlp_iteration_count", 0), };

Since HiGHS won't be using the cuPDLP-c timing, this can be commented out using a compiler directive. +## Making cuPDLP-c less chatty + +As a research code, `cuPDLP-c` naturally produces a lot of output. Within HiGHS it should produce less output, and it should be possible to make it run silently. The simplest way to do this is introduce a logging level parameter into `cuPDLP-c` that, when zero, yields no output, when 1 yields just summary logging at the end, and when 2 or more produces the logging that you would wish to see. I guess that this would be added to `CUPDLP_INT_USER_PARAM_INDEX`. + +A related issue is the use of `fp` and `fp_sol`. HiGHS won't be using these, so I set them to null pointers. `cuPDLP-c` already doesnt print the solution if `fp_sol` is a null pointer, so (like me) I suggest that the call to `writeJson(fp, pdhg);` is conditional on `if (fp)`. + ## Handling infeasible or unbounded problems cuPDLP-c now terminates with status `INFEASIBLE_OR_UNBOUNDED` for the infeasible and unbounded LPs in unit tests `pdlp-infeasible-lp` and `pdlp-unbounded-lp` in `highs/check/TestPdlp.cpp`.

Download the HiGHS source code and run -```bash +```sh pip install . ``` - from the root directory. The HiGHS C++ library no longer needs to be separately installed. The python package `highspy` depends on the `numpy` package and `numpy` will be installed as well, if it is not already present. -#### Testing - -The installation can be tested using the small example [call_highs_from_python_highspy.py](https://github.com/ERGO-Code/HiGHS/blob/master/examples/call_highs_from_python_highspy.py), yielding the output - - Running HiGHS 1.7.0 (git hash: n/a): Copyright (c) 2024 HiGHS under MIT licence terms - LP has 2 columns 2 rows and 4 nonzeros - Solving... - Problem solved. - - Model status = Optimal - Optimal objective = 1.0 - Iteration count = 0 - Primal solution status = Feasible - Dual solution status = Feasible - Basis validity = Valid - -or the more didactic [call_highs_from_python.py](https://github.com/ERGO-Code/HiGHS/blob/master/examples/call_highs_from_python.py). - -#### Google Colab Example - -The [Google Colab Example Notebook](https://colab.research.google.com/drive/1JmHF53OYfU-0Sp9bzLw-D2TQyRABSjHb?usp=sharing) demonstrates how to call HiGHS via the Python interface `highspy`. +The installation can be tested using the small example [call_highs_from_python_highspy.py](https://github.com/ERGO-Code/HiGHS/blob/master/examples/call_highs_from_python_highspy.py). +The [Google Colab Example Notebook](https://colab.research.google.com/drive/1JmHF53OYfU-0Sp9bzLw-D2TQyRABSjHb?usp=sharing) also demonstrates how to call `highspy`. ## Reference - If you use HiGHS in an academic context, please acknowledge this and cite the following article.

HiGHS must be able to run with less logging output, or completely silently. This is achieved using the `nLogLevel` parameter in `cuPDLP-c`.
