April 12, 2014: Here's another problem solvable by by our Brute
Force program which applies exhaustive search matching possible values with
variables in a set of equations.
Brute Force Version 3.1 adds the absolute value function, "abs", to
equation formats to enable solving the "Billiard Balls" problem. The
problem is to arrange 10 billiard balls into a triangle meeting a set of rules
about the balls numbered 1 through 10. One of the constraints is that the
balls in a particular row all have numbers more than 1 away from their
neighbors. This constraint for balls with numbers "a" and "b"
can be expressed with the equation "abs(ab)>1". Sample problem
BilliardBalls.prb is included with the download and is solved in about one
second.
