Seventeen lines and one-hundred-and-one points
In his paper "Seventeen lines and one-hundred-and-one points", Woeginger describes a
simple a polynomial-time algorithm to find the solution of the following curious
"Given two positive integers S and Q, does there exist a sequence of positive integers
that add up to S and whose squares add up to Q?"
Along with this problem, he presents a second one about arranging m lines in the
Euclidean plane in a way that there are exactly n points of intersection.
In this talk, I present the two problems, their connection, the algorithm along with its
analysis and the outlook to other problems.
