What exactly is an algorithm? Algorithms explained | BBC Ideas

What is an algorithm? You may be familiar with the idea in the context of Instagram, KZbin or Facebook, but it can feel like a big, abstract concept. Here’s presenter Jon Stroud with a step-by-step guide to what algorithms actually are, what algorithms do, and how algorithms work.

I'm a welder.... I got very tired of welding 'daylight' when it came to the welding of nodes or intersections of pipes of different sizes and at different angles. No matter how carefully each piece was cut by the fabricator, there would always be gaps and sometimes big gaps..... I started writing algorithms which produced the template patterns needed and these templates were accurate to less than .040". I spent years writing algorithms which gave answers to every conceivable piping intersection or connection or transition or offset or whatever was humanly possible in this area. All on a pocket computer which proved its magic on any worksite anywhere. And never again did I ever have to weld 'daylight'.

Sorry bro, you wrote a chain of instructions for your machine. Its a basic computer program. Make your templates in autocad, that program is full of mathematical and geometrical algorithms.

What an insightful video! Thank you so much for your sharing. You have done a lot of research and interviews with algorithm experts. What I learn from your video is that algorithms are a set of instructions. They help us to find related information in the search engines quickly and effectively. People should not be frightened of algorithms because they are beneficial to us. More importantly, we should learn how to utilize them in the proper manner.

Algorithms can also be mathematical with total absence of computers. The term "KZbin algorithm" or "TikTok algorithm" or "whatever algorithm" for that matter is inaccurate but has been accepted to explain "operationalized AI models" mostly in the form of "recommendation systems" aka "recommender systems". Algorithms simply are the building blocks of those "models" or "AI models". For the lay, the term "algorithm" has been deemed to be perhaps the most understandable. Algorithms can also refer to completed programming codes or scripts which may or may not use "historical data".

in ancient math books, problems do not state like in today's book. they usually came in form of general solutions for certain types of problems. I.e. Do these n steps and you get this result. it is named after Muhammad al-Khwarizmi a Persian polymath

The word "algorithm" comes from 8th century *Muslim mathematician, Al Khwarizmi.* he is the inventor of algorithm.

would be nice if they were transparent about what frameworks and variables they use in the algorithm. The internet was more free before they started making the decisions for 'us'...

[@klavdjojuvinsky7081]

It´s hard to understand what is an algorithm if you don´t show graphicaly how they work or are used to compose an instruction, for example. The video lacks that.

[@sanjeevsarpal357]

A sweet film, but algorithms are actually a mathematical receipe rather than a set of flying rules. For the drone example, the rules needed to make the drone fly and flip would use various algorithms.

[@user_cv8wysmstt]

ok let's be frank, we are all here not because of the youtube recommendation algorithm.

[@dipakbose2677]

The algorithm means steps to solve a mathematical problem. Those who do not understand any mathematics can make a hue and cry about algorithm without saying what mathematical problem he is going to solve.

He says that the thing we all should be concerned about is what happen when you are in the black box? He means he's pretty much accepting that algorithms and how they work still out of his reach
