WORK SCHEDULE FOR CS 4440 -- Spring 2023

The first day of CS 4440 classes is Thursday, January 26. 🌷

There are two sections of Theory of Algorithms (CS 4440). Both meet on Tuesdays and Thursdays.

🌸 Section 002 (the eleven o'clock class) meets from 11:00 to 12:15, in Bizzini 210
🌺 Section 001 (the two o'clock class) meets from 14:00 to 15:15, in Bizzini 103.


• Reading Assignment:
  • Read the course description & this schedule (important!!)
