Much ado about two (pearl): a pearl on parallel prefix computation
This pearl develops a statement about parallel prefix computation in the spirit of Knuth's 0-1-Principle for oblivious sorting algorithms. It turns out that 0-1 is not quite ...

Short proofs for cut-and-paste sorting of permutations
We consider the problem of determining the maximum number of moves required to sort a permutation of [n] using cut-and-paste operations, in which a segment is cut out and then pas...

Listing All Parsimonious Reversal Sequences: New Algorithms and Perspectives
In comparative genomics studies, finding a minimum length sequences of reversals, so called sorting by reversals, has been the topic of a huge literature. Since there are many mini...

Perfect trees and elementary embeddings
An important technique in large cardinal set theory is that of extending an elementary embedding j : M N between inner models to an elementary embedding j : M[G] N[G] between ge...
