	Title	Finite Horizon Analysis of Stochastic Systems with the Mur$\varphi$ Verifier			Type	Conference Article
	Year	2003	Publication	Theoretical Computer Science, 8th Italian Conference, ICTCS 2003, Bertinoro, Italy, October 13-15, 2003, Proceedings	Abbreviated Journal
	Volume		Issue		Pages	58-71
	Keywords
	Abstract	Many reactive systems are actually Stochastic Processes. Automatic analysis of such systems is usually very difficult thus typically one simplifies the analysis task by using simulation or by working on a simplified model (e.g. a Markov Chain). We present a Finite Horizon Probabilistic Model Checking approach which essentially can handle the same class of stochastic processes of a typical simulator. This yields easy modeling of the system to be analyzed together with formal verification capabilities. Our approach is based on a suitable disk based extension of the Mur$\varphi$ verifier. Moreover we present experimental results showing effectiveness of our approach.

	Title	On Placing Skips Optimally in Expectation			Type	Conference Article
	Year	2008	Publication	Web Search and Web Data Mining (WSDM 2008)	Abbreviated Journal
	Volume		Issue		Pages	15-24
	Keywords	Information Retrieval
	Abstract	We study the problem of optimal skip placement in an inverted list. Assuming the query distribution to be known in advance, we formally prove that an optimal skip placement can be computed quite efficiently. Our best algorithm runs in time O(n log n), n being the length of the list. The placement is optimal in the sense that it minimizes the expected time to process a query. Our theoretical results are matched by experiments with a real corpus, showing that substantial savings can be obtained with respect to the tra- ditional skip placement strategy, that of placing consecutive skips, each spanning sqrt(n) many locations.
