As far as I understand, the PATH solver converts the MCP into an equation, say `f(x)=0` and then applies a special Newton's method. The residual is the value of `f(x)`...

Thanks for notifying me. I'll watch the change closely.

According to [TSPLIB-DOC](http://akira.ruc.dk/~keld/research/LKH/LKH-2.0/DOC/TSPLIB_DOC.pdf), all distance functions return integer values. Coordinates can be floating, but distances are integral.

@legohyl When you input floating point coordinates, if the distance between two point is less than 0.5, then the distance is computed as zero. So, it is possible the shortest...

See https://github.com/jvkersch/pyconcorde/issues/29 Multiplying a large constant, say 1000, to the coordinates would resolve the issue.

Another option might be using the executable [`concorde.exe`](http://www.math.uwaterloo.ca/tsp/concorde/downloads/codes/cygwin/concorde.exe.gz) provided by the Concorde author. Combining with a cygwin DLL, I was able to run the executable on Windows through a subprocess...

Indeed. `inv(B)` was used just for education purpose. Perhaps I should also add `B\b`. Thanks.

Yes, this is by PATH. I'm not sure what can be done for this. Perhaps it's possible to suppress all messages. I don't think it's possible to hide only particular...

Have you tried running `cmake` in Spyder? Or, have you tried installing `hygese` in the Windows Powershell?
