For people interested, Richard Bellman who apparently came up with the name, put down the story in his autobiography which is cited on wikipedia: https://en.wikipedia.org/wiki/Dynamic_programming#History https://en.wikipedia.org/wiki/Dynamic_programming#History
"I spent the Fall quarter (of 1950) at RAND. My first task was to find a name for multistage decision processes. An interesting question is, "Where did the name, dynamic programming, come from?" The 1950s were not good years for mathematical research. We had a very interesting gentleman in Washington named Wilson. He was Secretary of Defense, and he actually had a pathological fear and hatred of the word "research". I’m not using the term lightly; I’m using it precisely. His face would suffuse, he would turn red, and he would get violent if people used the term research in his presence. You can imagine how he felt, then, about the term mathematical. The RAND Corporation was employed by the Air Force, and the Air Force had Wilson as its boss, essentially. Hence, I felt I had to do something to shield Wilson and the Air Force from the fact that I was really doing mathematics inside the RAND Corporation. What title, what name, could I choose? In the first place I was interested in planning, in decision making, in thinking. But planning, is not a good word for various reasons. I decided therefore to use the word "programming". I wanted to get across the idea that this was dynamic, this was multistage, this was time-varying. I thought, let's kill two birds with one stone. Let's take a word that has an absolutely precise meaning, namely dynamic, in the classical physical sense. It also has a very interesting property as an adjective, and that is it's impossible to use the word dynamic in a pejorative sense. Try thinking of some combination that will possibly give it a pejorative meaning. It's impossible. Thus, I thought dynamic programming was a good name. It was something not even a Congressman could object to. So I used it as an umbrella for my activities."
- rory 5y agoI originally had trouble with this term because I learned about it after learning the unrelated (afaict) terms "dynamic programming language" and "dynamic typing". So perhaps it's not so much that dynamic programming was a bad choice when it was named, but that we've overloaded the term "dynamic" too much since then.
- da39a3ee 5y agoHang on, did you read the quote above from the guy that named it?! He says explicitly that he chose it not because it was accurate but because non-technical employers/funders would be unlikely to object since it sounds positive. Does that not meet your definition of "bad choice" for a technical term? "dynamic programming language" means a "dynamically typed" language; and "dynamically typed" means the types are acquired at run time, and vary at run time according to run time events. So "dynamic" is a good choice there in that it is consistent with the use of the word outside programming.
