Finding Planted Partitions in Nearly Linear Time using Arrested Spectral Clustering
We describe an algorithm for clustering using a similarity graph. The algorithm (a) runs in O(n log3 n + m log n) time on graphs with n vertices and m edges, and (b) with high pro...

Any Domain of Attraction for a Linear Constrained System is a Tracking Domain of Attraction
We face the problem of determining a tracking domain of attraction, say the set of initial states starting from which it is possible to track reference signals in given class, for...

Maximum Gain Round Trips with Cost Constraints
Searching for optimal ways in a network is an important task in multiple application areas such as social networks, co-citation graphs or road networks. In the majority of applicat...

Timed automata with observers under energy constraints
In this paper we study one-clock priced timed automata in which prices can grow linearly ( ˙p = k) or exponentially ( ˙p = kp), with discontinuous updates on edges. We propose E...

A Stronger LP Bound for Formula Size Lower Bounds via Clique Constraints
We introduce a new technique proving formula size lower bounds based on the linear programming bound originally introduced by Karchmer, Kushilevitz and Nisan [11] and the theory of...
