Given a continuous function f : Sn-1 --> R, we consider the minimization of the functional
Integral over partial A of f (nA) dHn-1
with respect to the subset A of Rn, included in a class of convex bodies defined by surface or shape conditions. This corresponds to non-parametric formulations of older problems, including Newton's problem of the body of minimal resistance, following an approach due to G. Buttazzo and P. Guasoni [J. Convex Analysis 4 (1997) 343--351]. We establish existence and uniqueness results and some characterizations of the minimizers.
