** Derivative Free Optimization by a Hybridization of Methods**:: March 2011 - April 2012

A version of the BLX-Alpha genetic algorithm is hybridized with the Nelder-mead local search method. The hybrid is created by a relay implementation between the genetic algorithm and Nelder-Mead when stalling is detected. BLX-Alpha, Nelder-Mead, and the hybrid of the two are then tested on two classical engineering problems as well as on an experimental extrusion filter design. Numerical results are compared with known optimal solutions for the engineering problems and with previously published results for the multilayer extrusion filter design.

**:: May 2010 - August 2010**

*Immersed Interface Boundary Method*This project focused on understanding the IIM method as well as creating a program to implement it in 2 and 3D. IIM is a second order accurate method of solving a Poisson Elliptic differential equation with possible discontinuities in both the first and second derivatives. It is superior to Peskin's Immersed Boundary method which is only first order accurate in most cases due to smoothing or smearing discontinuous sections.

**:: January, 2010 - May, 2010**

*Shortest Distance Algorithm Applied to Tile Maps*Tiled maps create a problem for a shortest distance algorithm such as Djikstra's due to creation of a tree with an overabundance of edges. By weighting each vertex on the map by considering adjacent obstructions, a method is developed that eliminates edges in an efficient manner. The result is that Djikstra's Algorithm can now be applied to a tile set.

*Design of a Traffic Roundabout[COMAP]*A traffic circle or roundabout is a traffic control mechanism used to control traffic in an efficient and safe manner. These designs minimize the potential conflicts between vehicles by having traffic continually flow in a clockwise direction. Traffic is consistently flowing around the roundabout which should ideally reduce congestion in and around the roundabout. At most roundabouts, the incoming traffic must yield to the traffic in the circle, but others may use traffic lights or place the yield sign within the traffic circle giving priority to the incoming traffic. Our model is used to find the best traffic control mechanism for each of the incoming lanes with respect to the effect that it will have on the other incoming traffic lanes and other intersections in the city.
