Special Thank You, and Supporter Access!

Thank you very much for your support. At this level, any newly produced videos will include your name in the description of the video (or, if appropriate in the video itself) as a supporter of this work; on support, Daniel Page will reach out to you in case you wish to not be named, or if you have a particular name you would like Daniel Page to use. Regardless, a video shout of those that wish to be acknowledged will be made on a regular update video on the YouTube channel.

In addition, you will be given priority when making fan video requests. Daniel Page reserves the right to determine if the topic is appropriate for the channel, or something Daniel Page would like to do. Also, you will get access to polling for future video content.

You will get access to the 1st Steps to Computer Programming Using Java notes.

General Support

At this tier, you will gain access to all written notes in free video content provided by Dr. Page. Notes are in digital format. You will all rewards of tiers lower to this one.

Reward: You receive your own full digitally-signed PDF copy of Daniel Page's newest book, Advanced Data Structures: An Introduction to Data Structures and Algorithms. This 160 page book is the written note companion to Daniel's 33-part video lecture series of the same name (Advanced Data Structures). It is great for accessibility purposes, should one want a supplemental resource or simply a book with all the content in it. This book is available in other formats such as physical paperback and in kindle format on Amazon.

Pi Day 2022 - Invited Talk!
https://youtu.be/2O1b6UBqDgQ

In the study of algorithms, we desire provably-correct algorithms that efficiently solve problems.  In this talk, the area of approximation algorithms is introduced in the context of determining the existence of efficient algorithms for hard optimization problems.  If P is not equal to NP, which is one possibility for the outstanding and fundamental P vs. NP problem, then for some intractable problems there may only exist polynomial-time algorithms that can compute approximately close answers to optimal solutions, but no better than multiplicatively by some “magic number”.  The talk will briefly introduce a mixture of algorithms, computational complexity theory, and recent developments focusing on intractable problems intersecting scheduling and graph theory.

On March 14, 2022 I delivered this talk for University of Regina's Pi Day Event (with the Dept. of Math & Stats), organized by the Mathematics, Actuarial Science, and Statistics Student Society (MASS).  I am very thankful for their invitation to give this talk!  Thank you for the time to talk about Algorithms!

Remark:  I did not mention it properly given the time constraints, but Svensson in 2010 proved P|prec|Cmax has no 2-\epsilon approximation algorithm, relying on assumptions of a variant of the Unique Games Conjecture.  So if you believe that variant is true, then List Scheduling is optimal with respect to the approximation ratio!

Have a beautiful day!
