This paper presents an algorithm for the minimization of a nonlinear objective function subject to nonlinear inequality and equality constraints. The proposed method has the two distinguishing properties that, under weak assumptions, it converges to a Kuhn-Tucker point for the problem and under somewhat stronger assumptions, the rate of convergence is(More)
In this paper a method is described for solving linearly constrained nonlinear programming problems without evaluating any derivatives of the objective function. The algorithm uses the concept of active constraints and avoids the calculation of derivatives by approximating modified gradients and Hessian matrices by the aid of differences of function values.(More)
This paper explores a dialogue between art and technology in the fields of interactive art, interface design and interactive music. These fields create a frame in which I present my creative project Ephemeral Gumboots, a hybrid media artwork/musical instrument that takes South African Gumboot dance and extends it as an interface into an electronic(More)
