Perfect codes in Cartesian products of hypercube and multidimensional grid
Electronic Notes in Discrete Mathematics, 2005 Abstract We introduce and study a common generalization of 1-error binary perfect codes and perfect single error correcting codes in Lee metric, namely perfect codes on products of paths of lenght 2 and of infinite lenght. Both existence and inexistence results are given. The generalization to multiple error perfect code will also be mentioned.

Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)
Advanced Intelligent Systems, EarlyView.This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

High-order interpolation between adjacent cartesian finite difference grids of different size [PDF]
, 2020 Nested cartesian grid systems by design require interpolation of solution fields from coarser to finer grid systems. While several choices are available, preserving accuracy, stability and efficiency at the same time require careful design of the ...
