Book Review : Algorithms to live by

This book came up in the circles of job search and discussions of things that don’t matter.

It would have been a fallacy if the title said stood by what it said. Algorithms are thought processes and having behavioral philosophies of itself, that mathematicians may appreciate better. However, math being a yesteryear wonder-keyword and a dreaded subject across the globe. It may be better marketing tactics that prevailed over the political correctness, which is may be why the book is titled so.

The beginning of the book tries to shake the forgotten skills of probability and experience with uncertainty, the only use of probability theorems. The book is divided nicely in chapters that are digestible and probably demand a time of rest to rethink and re-iterate.  Game theory could be claimed as child of mathematics, logic, probability or computer science. As I mentioned , I could not think of computer science as something beyond mathematics. Somehow, the term “computer” make it technically appealing rather than the old school math. I feel same about control engineering leading to systems engineering, leading to mechatronics and robotics, and cyber physical systems  graduating into internet of things. More recently,  probability giving space to artificial intelligence and expert systems, to machine learning and deep learning and what not down the line.

Quotes I want to remember:

“In the practical use of our intellect, forgetting is as important a function as remembering” – William James

I was asked to draw my learning curve of whiteboard during an interview. I drew a upward going zigzag. My Y axis being “knowledge’ and X axis “time”, (this happened before I read this book) .I explained that my knowledge increases and shown by an upward slope and then I remove what I do not want reach a local minima and continue to pick up from there, leading to another maxima, again throwing away things I do not want and keep going. Some of my friends were impressed by this answer. Interviewer definitely had not seen such a learning curve, and I did not land up with a job offer.

Future reading:

“The Oligarchs” – David Hoffman – on optimal stopping

“Organizing from the Inside Out” – Julie Morgenstern

“Keeping Found things Found” – William Jones

I had read ” Eat that Frog” . This book compares some title in a single shot such as “The Now Habit” ( schedule leisure than work first), “Wait” ( dangling unfinished tasks), “Getting Things Done”. And then the classic Lao Tzu kicks in ” Do the difficult things while they are easy and do the great things while they are small”.  This chapter simply opens up the thoughts into scheduling ideas than I have used on my own. And it is as expected a nice mix of all these and similar techniques with minimal regret as the first priority..

Another interesting term that came up when reading the book is QED. Unlike Quantum ElectroDynamics, my friend expanded it was “Quite Easy Decision” (QED). While  the book describes Charles Darwin’s algorithm and conclusion to marry being written as “Quad erat demonstrandum“, which translates to “Hence proved”. Remember our school math ?!

The book also gives insights into the optimization problem that shows itself in mathematics, industrial engineering, operational research and project management. The origins of “traveling salesman problem” and why it was not called “prairie lawyer problem” was an interesting read. It was also mind-blowing to learn that the word “Serendipity” is derived from the fairy tales of “The Three Princes of Serendip” ( Serendip standing for Srilanka).

About the book:

Sans the notes the book is average at 262 pages. Reading is heavy with examples and intellectually simulating. This will make the reader think and read. Making the reading time longer than fiction. If the reader has used or searched about some productivity tools and thoughts then this book is interesting.
