======Algorithms, Fall 2022====== This course provides an introduction to the design and analysis of computer algorithms, with a particular emphasis on the use of **principles of mathematical induction** in designing algorithms. Its goal is to acquaint the students with basic computer algorithms and their design principles and to cultivate the students' ability in designing and analyzing algorithms independently. =====Announcements===== * 01/04: grade report available (revised 01/08); please send inquiries, if any, to the instructor by 2PM 01/06 (Fri.). * 12/15: the draft of Suggested Solutions to Final 2021 Problems revised. * 12/13: a draft of {{courses:alg2022:alg2021final_s20221215.pdf|Suggested Solutions to Final 2021 Problems}} available (revised 12/15). * 12/12: {{courses:alg2022:alg2022mid_s.pdf|Suggested Solutions to Midterm Problems}} revised for Problem 10. * 12/05: {{courses:alg2022:hw10.pdf|HW#10}} due on 12/13. * 12/05: notes/slides for NP-Completeness available. * 12/05: notes/slides for Reduction available. * 11/28: {{courses:alg2022:hw9.pdf|HW#9}} due on 12/06. * 11/28: notes/slides for Dynamic Programming available. * 11/24: notes/slides for Basic Graph Algorithms revised. * 11/21: {{courses:alg2022:hw8.pdf|HW#8}} due on 11/29. * 11/21: an illustration of Computing SCCs Using DFS is available. * 11/07: {{courses:alg2022:hw7.pdf|HW#7}} due on 11/16. * 11/07: notes/slides for Advanced Graph Algorithms available. * 11/07: {{courses:alg2022:alg2022mid_s.pdf|Suggested Solutions to Midterm Problems}} available. * 10/31: notes/slides for Basic Graph Algorithms available. * 10/17: {{courses:alg2022:hw6.pdf|HW#6}} due on 11/01. * 10/17: notes/slides for String Processing available.
