    Applications of Genetic Programming to Finance and Economics: Past, Present, Future

    While the origins of Genetic Programming (GP) stretch back over fifty years, the field of GP was invigorated by John Koza’s popularisation of the methodology in the 1990s. A particular feature of the GP literature since then has been a strong interest in the application of GP to real-world problem domains. One application domain which has attracted significant attention is that of finance and economics, with several hundred papers from this subfield being listed in the Genetic Programming Bibliography. In this article we outline why finance and economics has been a popular application area for GP and briefly indicate the wide span of this work. However, despite this research effort there is relatively scant evidence of the usage of GP by the mainstream finance community in academia or industry. We speculate why this may be the case, describe what is needed to make this research more relevant from a finance perspective, and suggest some future directions for the application of GP in finance and economics

    LiNbO3 optical waveguides deposited on sapphire by electric-field-assisted pulsed laser deposition

    Oriented LiNbO3 films have been grown on sapphire (1 1 0 2) substrates by low electric-field-assisted pulsed laser deposition. KrF excimer laser (248 nm) has been utilized for the ablation of monocrystalline stoichiometric target. The deposition was performed at all substrate temperatures in the range of 550–800°C in an oxygen atmosphere. The ablation threshold of 2.5 J/cm2 for the monocrystalline target was determined from the experimental results presenting ablation rate vs. laser fluence dependence. Electro-optical properties of these films appeared to be strongly dependent on the process parameters (substrate temperature, oxygen partial pressure, electric field), demonstrating the importance of the epitaxial growth control during the deposition. The films structure and morphology were characterized by XRD and AFM, respectively. The waveguide properties of the films were studied experimentally
