Spatial reasoning and planning is a core constituent in robotics, graphics, computer-aided design, and geographic information systems.

After a review of previous work in the related areas, Liu and Daneshmend present here a unified framework for qualitative spatial representation and reasoning, which enables the generation of solutions to spatial problems where the geometric knowledge is imprecise. The approach utilizes qualitative spatial representation and reasoning integrated with a quantitative search procedure based on simulated annealing. Many graphical illustrations and detailed algorithm descriptions help the readers to comprehend the solution paths and to develop their own applications.

The book is written as a self-contained text for researchers and graduate students in computer science and related engineering disciplines. The methodologies, algorithmic details, and case studies presented can be used as course material as well as a convenient reference.

Specially designed features that will help readers to understand and apply the techniques presented Balanced emphasis on recent and pioneering work as well as on theoretical aspects and practical applications Unifying engineering-oriented approach together with case studies and comprehensive examples Detailed algorithms and many illustrations for explanation Includes supplementary material: sn.pub/extras
