 OFFSET 1,2 LINKS Table of n, a(n) for n=1..62. W. M. Boyce, On a simple optimal stopping problem, Discr. Math., 5 (1973), 297-312. L. A. Shepp, Explicit solutions to some problems of optimal stopping, Ann. Math. Statist. 40 (1969) 993-1010. EXAMPLE a(5)=7 since if you have 5 plus balls and 7 minus balls, your expected gain in the Shepp Urn game is still positive, namely 0.15, but if you have 8 minus balls, the expectation is zero, so you quit.
