The relevant prefixes of coloured Motzkin walks: An average case analysis
In this paper we study some relevant prefixes of coloured Motzkin walks (otherwise called coloured Motzkin words). In these walks, the three kinds of step can have , and colours...

Pushing Random Walk Beyond Golden Ratio
We propose a simple modification of a well-known Random Walk algorithm for solving the Satisfiability problem and analyze its performance on random CNFs with a planted solution. ...

Hardness for Explicit State Software Model Checking Benchmarks
Directed model checking algorithms focus computation resources in the error-prone areas of concurrent systems. The algorithms depend on some empirical analysis to report their per...

Efficient Second-Order Iterative Methods for IR Drop Analysis in Power Grid
Due to the extremely large sizes of power grids, IR drop analysis has become a computationally challenging problem both in terms of runtime and memory usage. It has been shown in [...
