Applications of computational geometry In my work at Mentor Graphics, I have applied computational geometry algorithms and concepts on several occasions. Often, new development and customizations of general algorithms to specific new subfields of geospatial science are needed, such as transport and mobility, smart cities, agriculture, public health, disaster management, and social networks. We develop new techniques that lead to new and improved lower bounds for simplex range reporting as well as some other geometric problems. �TOf��ۺ����^?偮��ɣu���(&��jV��� ���e�p�u ��Tm��U��f�e��\o)�kJi��÷x��s\94Ai�����Np���Љ8zJ!I$�9&9�>��u�)ɜC�����G)k%G�F�=��� Z��M.ٷv=�u������R�����5]U��(@�B�{#����[}��`C�Ĉ��]������R-��>�Cا�YU���P�Ƹ*�LM��Yo��� /�y�^I�I�9ׅ@d��n9?�*��d�'���*���R*�GN�%��2�aU�,��:���\F� succeed, the matching must be realizable by planar, non-crossing Bibliography: The main textbook of the course is: Computational Geometry: Algorithms and Applications (CGAA), 3rd edition by M. de Berg, M. van Kreveld, M.
