1. A method for computer-assisted determination of an optimum-fuel control of nozzles according to a control instruction b=Ax, whereby b represents a desired m-dimensional forces/torque vector, A represents an m_×_n-dimensional nozzle matrix, and x represents a sought n-dimensional nozzle control vector and the nozzle control vector should meet a minimization criterion of J := ∑ i = 1 i = n ⁢ x i → min , the method comprising: computer generating a defined matrix transformation of starting constraints for a mass flow of the nozzles and of the minimization criterion takes place in a computer assisted manner; data processing a representation of a geometric description of the matrix transformation of starting constraints; searching, with a computer-assisted geometric search procedure in vector space, limiting point sets of the geometric description of the starting constraints; and applying the matrix transformation of minimization criterion to the points of the limiting point sets.
