1. Exploration of polygonal environments
Sammanfattning : Several robotic problems involve the systematic traversal of environments, commonly called exploration. This thesis presents a strategy for exploration of finite polygonal environments, assuming a point robot that has 1) no positional uncertainty and 2) an ideal range sensor that measures range in N uniformly distributed directions in the plane.

2. From Art Galleries to Terrain Modelling --- A Meandering Path through Computational Geometry
Sammanfattning : We give approximation and online algorithms as well as data structures for some well studied problems in computational geometry. The thesis is divided into three parts. In part one, we study problems related to guarding, exploring and searching geometric environments. LÄS MER
3. Approximation and Online Algorithms with Applications in Computational Biology and Computational Geometry
Sammanfattning : The main contributions of this thesis are in the area of approximation and online algorithm design and derivation of lower bounds on the approximability for a number of combinatorial optimization problems with applications in computational biology and computational geometry. Approximation and online algorithms are fundamental tools used to deal with computationally hard problems and problems in which the input is gradually disclosed over time. LÄS MER
