In this paper we propose an accelerated version of the cubic regularization of Newton's method [6]. The original version, used for minimizing a convex function with Lipschitz-continuous Hessian, guarantees a global rate of convergence of order O(1/k exp.2), where k is the iteration counter. Our...

In this paper, we propose a second-order corrector interior-point algorithm for semidefinite programming (SDP). This algorithm is based on the wide neighborhood. The complexity bound is $${O(\sqrt{n}L)}$$ for the Nesterov-Todd direction, which coincides with the best known complexity results for...

In this paper, we have presented the second level nesting of Bonney's disposition model (Bonney, 1998) and examined the implications of higher level nesting of the disposition model in relation to the dimension of the parameter space. We have also compared the performance of the disposition...

O'Hara G. (2005) A journey without maps: the regional policies of the 1964-70 British Labour Government, Regional Studies 39 , 1183-1195. This paper examines four influences on British regional policy in the late 1960s: party politics in the context of the economic environment; the structure of...

The value of an innovative new seed technology is evaluated in a discrete stochastic programming framework for a representative farm in the northern Corn Belt. Temperature-activated polymer coated seed has the potential to increase net returns by reducing yield loss due to delayed planting and...
