In about the year 1979 (of the previous century) I entered a contest to win a 5 1/4 floppy drive for inventing the best algorithm for placing the most words from a given list of words into a grid of letters. My entry was written in assembler on a Motorola 6800 development system. As it turned out neither I nor anyone else came up with any better method than a guided exhaustive search, to the great dissapointment of the contest perpetrators. In never found out why they wanted this algorithm, but I suspect they were trying to efficiently create crossword puzzles. Or else it was the CIA trying to decode Communist radio signals.
