I tried to interest my students in this, but I don't think I got anywhere. It's sponsored by the L. V. Hackley Endowment for the Study of Capitalism and Free Enterprise at Fayetteville State Univesity. (I said to my students: that's in North Carolina; maybe you'd even have some home court advantage! But, apparently, nada.) Professor Stringham has even written a paper which might help students with how to proceed.
First prize is $2500 for the student(s) and another $500 for a sponsoring faculty member. And worldwide fame, I'm sure.
