On the exhaustive generation of convex permutominoes
Elisabetta Grazzini, Elisa Pergola, Maddalena Poneti
A permutomino of size n is a polyomino determined by a pair of permutations of size n+1, such that they differ in each position. In this paper, after recalling some enumerative res…
Production matrices and Riordan arrays
Emeric Deutsch, Luca Ferrari, Simone Rinaldi
We translate the concept of succession rule and the ECO method into matrix notation, introducing the concept of a production matrix. This allows us to combine our method with other…
Binary Matrices under the Microscope: A Tomographical Problem
A. Frosini, M. Nivat
A binary matrix can be scanned by moving a fixed rectangular window (submatrix) across it, rather like examining it closely under a microscope. With each viewing, a convenient meas…
Lattices of lattice paths
Luca Ferrari, Renzo Pinzani
We consider posets of lattice paths (endowed with a natural order) and begin the study of such structures. We give an algebraic condition to recognize which ones of these posets ar…
Discrete Tomography: Reconstruction under periodicity constraints
Alberto Del Lungo, Andrea Frosini, Maurice Nivat +1
This paper studies the problem of reconstructing binary matrices that are only accessible through few evaluations of their discrete X-rays. Such question is prominently motivated b…
