Combination of decision procedures is at the heart of Satisfiability Modulo Theories (SMT) solvers. It provides ways to compose decision procedures for expressive languages which mix symbols from various decidable theories. Typical combinations include (linear) arithmetic, uninterpreted symbols, arrays operators, etc. In [7] we showed that any first-order theory from the Bernays-Schönfinkel-Ram...

We prove a conjecture of Ackerman, Barequet and Pinter. Every floorplan with n internal segments can be embedded on every set of n points in generic position. The construction makes use of area universal floorplans also known as area universal rectangular layouts. The notion of area used in our context depends on a non-uniform density function. We, therefore, have to generalize the theory of ar...

Many theories of skill acquisition have had considerable success in addressing the fine details of learning in relatively simple tasks, but can they scale up to complex tasks that are more typical of human learning in the real world? Some theories argue for scalability by making the implicit assumption that complex tasks consist of many smaller parts, which are learned according to basic learni...

The Raspberry Pi-based AI car uses a 4-wheeled Ackerman wheeled robot as motion platform and is equipped with high-performance lidar. In the ROS system under Ubuntu18, test has passed cartographer mapping algorithm. After experiments, it found that algorithm can also present good superior effect Pi platform.
