In this talk, we present algorithms for solving the trilinear isomorphisms underlying ALTEQ and MEDS that improve upon previously known run time exponents by a constant factor. These algorithms inform the parameter selection in ALTEQ and MEDS and were already taken into account in the ALTEQ submission. Key ingredients in our algorithms are new distinguishing invariants under the respective actions. The run time analyses rely on certain heuristics, which are supported by experimental and theoretical evidence.
