Algebra | Variables (mathematics)
Board puzzles with algebra of binary variables ask players to locate the hidden objects based on a set of clue cells and their neighbors marked as variables (unknowns). A variable with value of 1 corresponds to a cell with an object. Contrary, a variable with value of 0 corresponds to an empty cell—no hidden object. (Wikipedia).
Simultaneous Equations - Tons of Examples!

Dana Richards - Algorithmic Puzzles and Martin Gardner- CoM Oct 2020
The vast majority of mathematical puzzles ask for the existence of a solution. It is merely an exercise when the method is known and it is more of a puzzle when the method is not clear. An algorithmic puzzle takes this further by only asking for the method itself or a property of the metho
