The topic of this project is content-based retrieval of 3D models that are represented as triangle meshes. An object from some 3D geometry database can traditionally be accessed using attached structural information such as textual annotation. However, there are frequent requirements for a content-based retrieval of various multimedia contents. A content-based 3D model retrieval system has been...

the analysis of flow in water-distribution networks with several pumps by the content model may be turned into a non-convex optimization uncertain problem with multiple solutions. newton-based methods such as gga are not able to capture a global optimum in these situations. on the other hand, evolutionary methods designed to use the population of individuals may find a global solution even for ...
