Counting Permutations Where The Difference Between Entries Located Places Apart Can never be (For any given positive integers and )
George Spahn, Doron Zeilberger
Given positive integers and , we use inclusion-exclusion, weighted-counting of tilings, and dynamical programming, in order to enumerate, semi-efficiently, the classes of pe…
Variations on the Missionaries and Cannibals Problem
George Spahn, Doron Zeilberger
We explore both automated and human approaches to the generalized Missionaries and Cannibals problem.
How does the Gerrymander Sequence Continue?
Manuel Kauers, Christoph Koutschan, George Spahn
We compute the next few terms of the OEIS sequence A348456 and provide guessed equations for the generating functions of some sequences in its context.
Enumerating solutions to grid based puzzles with a fixed number of rows
George Spahn
In this paper we demonstrate a method for counting the number of solutions to various logic puzzles. Specifically, we remove all of the "clues" from the puzzle which help the solve…
