To make a sustainable restoration of a historical centre it is necessary to understand, among other things, the materials used in the coatings of the buildings. In this w [...]

An efficient algorithm is presented for the formation of cycle bases of graphs corresponding to sparse cycle-member incidence matrices, leading to the formation of highly [...]

The city of Coimbra was the first capital of Portugal, in the 12th century. This city has archaeological remains from before the Roman time. The existing buildings predom [...]

Modifications of reinforcement learning algorithm, so called continuous action reinforcement learning automaton (CARLA), are presented in this contribution. Automaton lea [...]

The aim of the robot path planning is searching for a path from a start to a goal position without collisions with known obstacles minimizing length, difficulty and risk [...]

Bermond, Delorme and Farhi (1984) introduced the concept of a star product of two graphs and, in connection with degree diameter problem, investigated the diameter of a s [...]

For graphs F , G and H, we write F → (G, H) to mean that if the edges of F are colored with two colors, say red and blue, then the red subgraph contains a copy of G or [...]
