Hi there,
I've run into an assertion violation when I used CGAL/Optimal Transportation
Curve
Reconstruction(https://doc.cgal.org/latest/Optimal_transportation_reconstruction_2/index.html#Chapter_Optimal_Transportation_Curve_Reconstruction)
for 2D point reconstruction. The data I used is a set of simple 2D points
(already uploaded: 63_2D_points.txt
<http://cgal-discuss.949826.n4.nabble.com/file/t376067/63_2D_points.txt> ).
The program I used is the demo in CGAL-4.13/examples/Optimal Transportation
Curve Reconstruction_2/otr2_list_output_examples.cp. The main content is as
follows:
......
load_xy_file(filesPath, points);
Otr_2 otr2(points);
otr2.run_under_wasserstein_tolerance(0.8);
list_output(otr2);
......

The data I used is a very simple set of 2D points. What is the cause of this
assertion error? How can I avoid this assertion error?

Thanks!
