Hello, I am Ruyi Ji (吉如一). Welcome to my home page.
I'm now a first-year Ph.D. student in the Programming Language Lab (PLL) at Peking University, advised by Prof. Zhenjiang Hu and Prof. Yingfei Xiong. I am interested in program synthesis. Click here for more about my research.
I used to be a contestant in competitive programming. I won the 3rd place, Gold medal in ACM/ICPC World Finals 2018. Now I'm still engaging in relevant activities. I'm the founder and the first president of PKU Student Algorithm Association. Click here for more about our activities.
- December 6, 2020 PKU Student Algorithm Association successfully organized the 2020 SenseTime-Cup Programming Contest. This contest is jointly organized by us and BUPT ZhouXing Algorithm Association, and is supported by SenseTime.
- November 22, 2020 I'm invited to set problems for the 2020 ICPC China Beijing Xiaomi Invitational Programming Contest. 3037 teams participated in its online contest, and 103 among them advanced to the onsite.
- October 1, 2020 I'm excited that our paper Guiding Dynamic Programing via Structural Probability for Accelerating Programming by Example has been accepted at OOPSLA'20. This paper combines structural probability and dynamic programming to faster solve programming-by-example tasks. Our approach, MaxFlash, achieved 4x-2080x speed-ups against SOTA synthesizers.
