Welcome to the proceedings of the Third International Conference on Contemporary Computing, which was held in Noida (outskirts of New Delhi), India. Computing is an exciting and evolving area. This conference, which was jointly organized by the Jaypee Institute of Information Technology, Noida, India and the University of Fl- ida, Gainesville, USA, focused on topics that are of contemporary interest to computer and computational scientists and engineers. The conference had an exciting technical program of 79 papers submitted by - searchers and practitioners from academia, industry, and government to advance the algorithmic, systems, applications, and educational aspects of contemporary comp- ing. These papers were selected from 350 submissions (with an overall acceptance rate of around 23%). The technical program was put together by a distinguished int- national Program Committee consisting of more than 150 members. The Program Committee was led by the following Track Chairs: Arunava Banerjee, Kanad Kishore Biswas, Summet Dua, Prabhat Mishra, Rajat Moona, Sheung-Hung Poon, and Cho-Li Wang. I would like to thank the Program Committee and the Track Chairs for their tremendous effort. I would like to thank the General Chairs, Prof. Sartaj Sahni and Prof. Sanjay Goel, for giving me the opportunity to lead the technical program. Sanjay Ranka

This book constitutes the proceedings of the 11th International Workshop on Algorithms and Computation, WALCOM 2017, held in Hsinchu, Taiwan, in March 2017.
