Archit Bubna - 2019CS10331 (BTP1 + BTP2): Archit proved that the prophet problem with order selection has a strictly better competitive ratio than the prophet problem with random arrival order. This work was published in EC2023, a top tier conference. Archit completed his graduation with a perfect 10 CGPA and won the President's Gold Medal.


Nikhil Ayyadevara - 2017CS10330 (MTP), Galav Kapoor - 2018CS10332 (BTP1), Kalash Gupta - 2018CS10346 (BTP1), Navneel Singhal - 2018CS10360 (BTP1)


Nikhil Ayyadevara - 2017CS10330 (BTP1): Nikhil proved that the randomized competitive ratio of the weighted k-server problem is at least exponential in k, improving the previously known lower bound which was only ln(k). This work was published in ESA2021, a top tier conference. Nikhil is currently a Ph.D. student at University of Michigan.
