Optimally reliable payment flows: https://arxiv.org/abs/2107.05322
Probabilistic payment delivery: https://arxiv.org/abs/2103.08576
Piecewise linearization: https://lists.linuxfoundation.org/pipermail/lightning-dev/2022-March/003510.html
Proof that Piecewise linearization is a good strategy: https://hochbaum.ieor.berkeley.edu/files/ieor290-G.pdf (In general Dorit Hochbaum has a lot of useful lecture notes)
Pruning the problem: renepickhardt/mpp-splitter#12 (and issues arising from it)
A glossary and a well documented notebook with some outputs can be found at: https://github.com/renepickhardt/mpp-splitter/blob/pickhardt-payments-simulation-dev/Pickhardt-Payments-Simulation.ipynb

Most comprehensive source of original information is probably at: https://www.mit.edu/~dimitrib/home.html (The work body of Dimitri Bertsekas is truely impressive)
