Limits and Applications of Group Algebras for Parameterized Problems
The algebraic framework introduced in [Koutis, Proc. of the 35th ICALP 2008] reduces several combinatorial problems in parameterized complexity to the problem of detecting multili...

New Results in the Simultaneous Message Passing Model via Information Theoretic Techniques
—Consider the following Simultaneous Message Passing (SMP) model for computing a relation f ⊆ X ×Y ×Z. In this model Alice, on input x ∈ X and Bob, on input y ∈ Y, send o...

Limitations of Hardness vs. Randomness under Uniform Reductions
We consider (uniform) reductions from computing a function f to the task of distinguishing the output of some pseudorandom generator G from uniform. Impagliazzo and Wigderson [IW]...

Dynamic Wavelength Assignment Using Wavelength Spectrum Separation for Crosstalk Limited Networks
— As an optical signal propagates along a lightpath to its destination in wavelength-routed optical networks (WRONs), the quality of service (QoS) will be degraded by transmissio...
