In the area of applied optimisation, heuristics are a popular means to address computational problems of high complexity. Modelling the problem and mapping all variations of its solution into a so-called solution space are integral parts of this process. Representing solutions as graphs is common and, for a special type of graph, Prüfer Code (PC) offers a computationally efficient mapping (algorithms...
Most multi-robot task allocation algorithms are concerned with the allocation of individual tasks to single robots. However certain types of tasks require a team of robots for their execution, and for the allocation of such tasks non-conflicting robot teams have to be formed. Most of the existing allocation algorithms for such tasks mainly address the robot-team formation and the tasks are allocated...
In the recent decades an impressive progress was done in automation and robotic fields. Projects such as Google driverless car with “sense and avoid” capabilities or intelligent Unmanned Air Vehicle (UAV) are examples of interesting research works targeting a high degree of autonomy. In this context we underline the unavoidable requirement for improving path planning algo-rithms. Indeed, path planning...
Compact representation of integer values is a key feature for data compression. A compressed representation allows us to store more integers within less space, and therefore, to work in faster hierarchies of memory. Adaptive searching yields to compressed representations of integers. In scenarios where the cost of updating the encoding is high, approaches to perform operations over integers dynamically...
Web applications often use dynamic pages that interact with each other by accessing shared objects, e.g., session objects. Interactions between dynamic pages need to be carefully tested, as they may give rise to subtle faults that cannot be detected by testing individual pages in isolation. Since it is impractical to test all possible interactions, a trade-off must be made between test coverage (in...
