PROJECTS

Geometric algorithm Point location 3/2015-4/2015

Design efficient data structure algorithm using C language, based on Kirkpatrick’s idea to achieve O (log n) query time performance to check a point contain in the given triangles. The algorithm reconstructs the triangulation table by removing the vertex of degree six from independent set. The challenge part of the project is to handle triangulation use ear clipping method, construct link list triangulation table to keep track of relations between new triangles amount old triangles.

Django Mini-Flickr 2/2014-5/2014

Implement a web application that is similar to Flickr. It is based on Python Django framework. The application allows users to share their ideas, emotions and pictures with others. We implement a well-formed relational database and manage data flow with MVC design.
