A while ago I saw a paper in the SIAM Review - just one and a half pages of maths, followed by
"Remark 2. The theorem proved here gives a completely new general method. It generalizes all known results for balancing chemical equations cited chronologically in references [1]–[125]."

Reference 125 is to this paper.
- _delirium 11y agoIt's interesting that despite being long open, both the problem and the solution are stated using only elementary linear algebra.
- GFK_of_xmaspast 11y agoIn fairness, this paper is looking for integer solutions instead of SiRev's real ones.
- octonion 11y agoThis appears to be essentially equivalent to solving a linear system using the Moore-Penrose pseudoinverse. https://en.m.wikipedia.org/wiki/Moore%E2%80%93Penrose_pseudoinverse https://en.m.wikipedia.org/wiki/Moore%E2%80%93Penrose_pseudo...
