Igor PopovWe show that, in practice, it is rare that two collections of homology relationships are perfectly hierarchically related. Therefore we present an optimization problem to measure how far they are from being so. We show that this problem, which is a generalization of the assignment problem, is NP-Har

entioned by Bulteau and Weller in 2019 who asked whether, in polynomial time, one can decide if a common partition with block sizes at least two can be achieved without deleting any genes. We show that the problem is actually NP-hard for any fixed list of allowed block sizes, unless blocks sizes are

Characteristics of Shells of the Pearl Mussels in Accordance to “Comparatory Method”The forms corresponding to different species as described by the advocates of the “comparatory method”, as well as intermediate forms, can be found in any series of samples from one river. At least two, and usually all the three “comparatory species” occur together. The share of different forms varies among different populations.
