7 A bit of a Digression I think CLI is great. Innovation Learning Validation! More publicity? and a Larger Audience? 3

The objective was to improve the programming scenario in India. 2009 - The Start 7 We Launched The objective was to improve the programming scenario in India. 4

7 2017 - Today 13.7+ million submissions to various problems. 4,50,000+ registered users spread across the globe 12K+ educational institutions and 150+ countries use our platform. 1500+ contests hosted in the last 8 years. 6500+ problems based on ACM ICPC and IOI. 5

2017 - Today 7 India has the largest competitive programming community in the world The maximum traffic to most prominent programming contest websites across the globe comes from India CodeChef (77.3%), HackerRank(47.9%), Codeforces (37.3%) The largest ever ACM ICPC regional contest held - http://www.codechef.com/ACMIND16 (2925 teams, 21389 submissions made) Amritapuri regionals hosts the largest regionals and sees the maximum participation 6

7 CodeChef and ICPC In 2010, we launched our Go For Gold Initiative. We go to colleges and conduct orientations sessions about ICPC - In last 2 years alone we have been to over 75 colleges in the country. We started training faculty on using competitive programming and an online judge in teaching. We have been supporting ACM ICPC India regionals since last 7 years now. We reimburse travel to the participants of ICPC, encourage the RCD’s to invite more teams. 7

The sad state 7 While India contributes the highest in terms of sheer numbers to the competitive programming world, the quality of the top programmers from India is still far behind the top programming talent of countries like Russia, China, Poland, Ukraine and others 8
