Hello, My name is Guo Xing, I have sent a mail for some ideas on gsoc18 projects. David's uBLAS project on GPU computation is a little bit hard for me. Still thanks for his kind reply :) . These days, I found a project that I could possibly work on. So, I decide to take "Similarity between geometries". Below is my short self-introduction. Name: Guo Xing University: Southeast University Major: Electronic Engineering Email: higuoxing@gmail.com Github: https://github.com/higuoxing Homepage: https://higuoxing.com Availability: (Feb-Jun 4 hr/day) (Jun-Aug 6hr/day or more) As for my code competency, I will take the project 1 competency test after my final exam. Thank you! Regards, Guo Xing
