We consider a generalization of Heilbronn's triangle problem by asking, given any integers n=k, for the supremum @D"k(n) of the minimum area determined by the convex hull of some k of n points in the unit square [0,1]^2, where the supremum is taken over all distributions of n points in [0,1]^2. Improving the lower bound @D"k(n)=@W(1/n^(^k^-^1^)^/^(^k^-^2^)) from [C. Bertram-Kretzberg, T. Hofmeister, H. Lefmann, An algorithm for Heilbronn's problem, SIAM Journal on Computing 30 (2000) 383-390] and from [W.M. Schmidt, On a problem of Heilbronn, Journal of the London Mathematical Society (2) 4 (1972) 545-550] for k=4, we show that @D"k(n)=@W((logn)^1^/^(^k^-^2^)/n^(^k^-^1^)^/^(^k^-^2^)) for fixed integers k=3 as asked for in [C. Bertram-Kretzberg, T. Hofmeister, H. Lefmann, An algorithm for Heilbronn's problem, SIAM Journal on Computing 30 (2000) 383-390]. Moreover, we provide a deterministic polynomial time algorithm which finds n points in [0,1]^2, which achieve this lower bound on @D"k(n).
