I'm facing an issue where a linear mixed model terminates at a saddle point for some datasets. I've tried to search for any prior discussion but was unable to find anything. The short version is that …

Find the saddle point for the matrix of order N. Saddle point is an element of the matrix such that it is the minimum element for the column to which it belongs. Saddle point for a given matrix is alw…

### Background
There is no transition state optimization (or, saddle-point optimization) implementation in ABACUS itself. Although we can use ASE-ABACUS interfaces to use the TS method in ASE or code…

It would be nice to implement a function which computes the algebraic intersection of two saddle connections (or closed curves which are unions of saddle connections if there are more than one singula…

Critical flaws have been found when recalculating saddles (From large multipoints). As well as walks from both multipoint and single point saddles.
Walk Issue:
From single points, we need to walk…

The following does not produce any saddle connections but raises an exception.
```py

SaddleOperator(opA, opM, opN; S = promote_type(storage_type.(opA, opM, opN)))
Creates saddle point l…
