Solving alu bar cut as Cutting Stock Problem (CSP) with Lpsolve in C#. Can work on MacOs (need import modification) or Window

• Call calRequiredBarWithFormat(...) for get string formated patterns.

Output e.g.

string[]
{
    "1000 40 1v 600 + 1v 200"
    "1000 10 1v 600 + 1v 200 + 1v 100"
}

• Call calRequiredBar(...) to get total number of required bar
• Call calRequiredBarCore(...) to get dictionary Dictionary<List<BarSet>, int>. Which is map of Patterns number of reuquired stock for each pattern.

NOTE: Each func re-calculates everything, we just need to use ONE suitable func.

This project come with build for Winx64 ddl. To build with MacOs, in ColumnGenerationSolver.cs, change using namespace to

// using "lpsolve_win"
using "lpsolve_macos"

This is just change the wrapper lib for .dll to .dylib on mac. 2 lib lpsolve55.dll & liblpsolve55.dylib is attached with src.

In case we need to build for Winx86 or other OS, download built lpsolve55.dll from lpsolve download page package lp_solve_5.5.2.5_dev_win32.zip etc.

Source code is tested under dotnet core and tested under MacOs.

cd test/CutOptimization.Tests
