Achieving minimum-cost multicast: a decentralized approach based on network coding
— We present decentralized algorithms that compute minimum-cost subgraphs for establishing multicast connections in networks that use coding. These algorithms, coupled with exist...

Parallel Split-Step Fourier Methods for the CMKdV Equation
The class of complex modified Korteweg-de Vries (CMKdV) equations has many applications. One form of the CMKdV equation has been used to create models for the nonlinear evolution...
