The Decidability of Simultaneous Rigid E-Unification with One Variable
We show that simultaneous rigid E-unification, or SREU for short, is decidable and in fact EXPTIME-complete in the case of one variable. This result implies that the fragment of i...

Discrepancy Sets and Pseudorandom Generators for Combinatorial Rectangles
A common subproblem of DNF approximate counting and derandomizing RL is the discrepancy problem for combinatorial rectangles. We explicitly construct a poly(n)-size sample space t...

Fault Tolerant Data Structures
We study the tolerance of data structures to memory faults. We observe that many pointerbased data structures (e.g., linked lists, trees, etc.) are highly nonresilient to faults. ...
