Hello. I have searched the archives but have not found anything. I need to solve a constrained optimisation problem for a nonlinear function (�maximum entropy formalism�). Specifically,
Optimise: -1*SUM(p_ilog(p_i)) for a vector p_i of probabilities, conditional on a series of constraints of the form: SUM(T_i*p_i)=k_i for given values of T_i and k_i (these are constraints on expectations). Can this be done in R?
