Solving Paint-by-Numbers Puzzles with Integer Programming by Robert Bosch The Article Here is a postscript file pbn.ps of the "Painting by Numbers" installment of Optima Mindsharpener (Optima 65). The Code The program pbn.c reads a file pbn.dat (which contains a description of a paint-by-numbers puzzle) and then constructs a file pbn.lp (which describes an integer program that can be solved, with CPLEX, to obtain the solution to the puzzle). Data Files The following files describe the paint-by-numbers puzzles that appear in the article: spaceman.dat : The spaceman puzzle displayed in Figure 1. dragonfly.dat : The puzzle displayed in Figure 5. Instructions To construct a CPLEX ".lp" file for the spaceman puzzle, copy the file spaceman.dat into the (initially nonexistent) file pbn.dat . Then compile the program pbn.c . When you run the program, it will read the file pbn.dat and construct a file pbn.lp If you have comments or questions, please e-mail bobb@cs.oberlin.edu Link to Bob Bosch's page.

Two Trains Trains travel from Foodletown to Myerville all day, always on the same track, always going nonstop and at the same speed. The noon train took 80 minutes to complete the trip, but the 4 PM train took an hour and 20 minutes. Why? Answer There is a cask of wine, and a larger barrel of water. I take a dipper of wine and add it to the water. Then I take a dipper of the water/wine mixture and pour it back into the wine barrel. Is there now more wine in the water, or more water in the wine? Answer Flags The great square fortress Fua stands on the level Dal Mahir plain where the straight east-west and north-south roads meet. Along the tops of the outer fortress walls there are flags on short flagpoles, such that a traveler approaching the fortress from any direction sees 3 flags. (It is not possible to see a flag which is not on a wall that you are facing directly.) How many flags are there altogether? You should give the smallest number possible.
