Abstract
We present a weighted version of Megiddo's multidimensional search tec hnique and use it to obtain faster algorithms for certain convex optim ization problems in R(d), for fixed d. This leads to speed-ups by a fa ctor of log(d) n for applications such as solving the Lagrangian duals of matroidal knapsack problems and of constrained optimum subgraph pr oblems on graphs of bounded tree-width.
