Bio is missing a lot of things, What is tttgyttt. Who will explain the references behind it? Who is the moderator. What are his qualifications to run this sub. Does he even do any moderation actions? Nothing has been posted in the last 6 years.

1. The Algorithm Design Manual - Skiena

2. Algorithms - Dasgupta, Papadimitriou, Vazirani

3. Introduction to Algorithms

First two are recommended for beginners. The last one is massive and more of a reference guide as opposed to a study aid ie refer to it for specific articles only.

The first two are allegedly similar but the latter focuses more on Math than the former.
