Approximating Submodular Matroid-Constrained Partitioning
The submodular partitioning problem asks to minimize, over all partitions P of a ground set V, the sum of a given submodular function f over the parts of P. The problem has seen considerable work in approximability, as it encompasses multiterminal cuts on graphs, k-cuts on hypergraphs, and elementary linear algebra problems such as matrix multiway partitioning. This research has been divided between the fixed terminal setting, where we are given a set of terminals that must be separated by P, a…

A very stupid workaround (as explained in the article, this has to be done at the factory to make it an officially different product), with the only goal to make it live harder for EV drivers by not offering card payments.

Bypassing the payment terminal with 49.9 kW: TMH sells HYC49 from Alpitronic - electrive.com
The Mobility House offers the Alpitronic Hypercharger HYC49, a fast charger with a maximum charging capacity of 49.9 kW. The model is actually a HYC50, but it
