The initial efforts of all participants in the newyears thread, and comparison and validation of the results produced by the three different approaches to the problem, have led us to agreement that we have indeed found a complete set of solutions. At least complete within the bounds of our combined ability to imagine and test generating expressions to this point!
Knowing what a complete solution set looks like, we have each shifted emphasis from the generating code, to a more critical...
Member Beryllos who originally opened the thread discovered that some solutions were missed (and possibly other invalid solutions included) as a result of math errors intrinsic to floating point math. They very correctly identified integer math, math using only integer fractions, as the necessary solution. In the face of some...

Way back around new year's day during the winter of '19 (remember that kiddies?), LQ member Beryllos posted a New Year Puzzle and programming challenge in the Programming forum.
The goal of the puzzle is to generate as many whole numbers as possible between 0 and 100 using only the digits of the year, 2,0,1 and 9 in simple constant arithmetic expressions such as 9 * (10 - 2).
For most of the past year I have encouraged others to make use of their LQ blog space as a place to post and manage code for their personal projects and interests which they wish to share with others.
Posting to our LQ blog space allows us to share our code and ideas without the posting constraints that apply within the question oriented fora, and also allows us to update, alter and extend that information over time without corrupting the logical development, or train of thought so...
