Scienze Fisiche & INFN – Istituto Nazionale di Fisica Nucleare)

39 Merlino The online analysis in Virgo has been tackled via Merlino, a SMFT-based (Static Matched Filter Technique) framework, whose architecture is sketched below. Merlino: Data Analysis via Matched Filters Bosis Merlino computes the correlation between the data series and a number of signal templates, obtained by simulating the chirp signals emitted by pairs of coalescing stars with solar masses within a given range. Precision and efficiency are strongly influenced by the number of considered working points, i.e. the granularity of the search in the space of the star masses. A Grid-based Evolution of Merlino

40 Adaptive Filters for Detection of Gravitational Waves in Virgo Data Size and Computational Cost of the Analysis Data from VIRGO are characterized by a very low SNR, and thus need to be accurately filtered to actually detect the presence of the signal. However an on-line analysis requires roughly 300 Gflops to retrieve the 90 per cent of the SNR. Approach to the Analysis via Adaptive Filters The aim is to implement a rough analysis with: small signal losses (w.r.t. the use of matched filters); robustness against false detections; low computational costs (for use in real-time). The idea is to use the adaptive IIR ALE filter to reconstruct at the output the coherent component at the input. The reconstruction can then be used as (noisy) template for building a correlation detector for the analysis. infinite impulse response adaptive line enhancer (IIR ALE)

41 A Genetic Parallel Evolution of the Price's Controlled Random Search Algorithm As most of the others, the Prices algorithm is based on a matched filter approach. However, instead of adopting a fixed grid of templates, it heuristically explores the search space via a controlled random search. Parallel Genetic Price Price algorithm has been modified to improve the performances and better ensure the thoroughness of the exploration of the search space - without having to consider a too high number of working points. To these aims we parallelized the software, and introduced a genetic modification of the search procedure, which introduce some randomness in the generation of new working points, thus making the software more resilient to local minima. Furthermore more than one trial point is now generated at each step. A number of different population members are randomly chosen, and each of them is reflected through the centroid of the others, generating a new trial point. These trial points are then compared to the worst population members, and substitute them in case of better behaviour.
