Is lamb parameter just weighting or is there more to it #61

Thanks for this library. This is more of a question than a bug.

Is lamb simply a weighting between euclidean and geodesic in the sense that one can calculate them separately and weigh or is there something else to it?

@PiaoR ? Is this some sort of spam or did you reply to the wrong thread?

It is indeed a simple weighting between Euclidean and Geodesic distances

For example see here: https://github.com/masadcv/FastGeodis/blob/0f6cc1e6e104bee56e6eb9dfdd2cfd29c21a1a3e/FastGeodis/fastgeodis_cpu.cpp#L107

And yes you can calculate lambda and use that value.
