an experimental chess engine developed by [[Mathieu Autonès]], [[Aryel Beck]], [[Phillippe Camacho]], [[Nicolas Lassabe]], [[Hervé Luga]], and [[François Scharffe]], using an [[Neural Networks|artificial neuronal network]] as [[Evaluation Function|evaluation function]] generated by a [[Genetic Programming#GeneticAlgorithm|genetic algorithm]]. Tempo applies [[https://en.wikipedia.org/wiki/L-system|L-systems]] as elaborated by [[Egbert Boers]] and [[Herman Kuiper]] <ref>[[Egbert Boers]], [[Herman Kuiper]] (**1992**). //Biological metaphors and the design of modular artificial neural networks//. Master’s thesis, [[Leiden University]], [[http://liacs.leidenuniv.nl/assets/PDF/boers-kuiper.92.pdf|pdf]]</ref>, to generate [[https://en.wikipedia.org/wiki/Modular_neural_network|modular neural networks]] whose size is independent of that of the [[https://en.wikipedia.org/wiki/Chromosome_%28genetic_algorithm%29|chromosome]] and [[https://en.wikipedia.org/wiki/Crossover_%28genetic_algorithm%29|crossover]] tolerant. A population of L-system construction rules is generated to mark the resulting networks according to their capabilities to [[Learning|learn]] game position evaluations from real games. Simple aspects were learnt at first. Strongest individuals learnt more complex faetures, from [[Material|material]] to [[Square Control|square control]] and [[Pawn Structure|pawn structure]] <ref>[[Mathieu Autonès]], [[Aryel Beck]], [[Phillippe Camacho]], [[Nicolas Lassabe]], [[Hervé Luga]], [[François Scharffe]] (**2004**). //[[http://link.springer.com/chapter/10.1007/978-3-540-24650-3_1|Evaluation of Chess Position by Modular Neural network Generated by Genetic Algorithm]]//.

=Abstract=
|| {{In this article we present our chess engine Tempo. One of the major difficulties for this type of program lies in the function for evaluating game positions. This function is composed of a large number of parameters which have to be determined and then adjusted. We propose an alternative which consists in replacing this function by an artificial neuron network (ANN). Without topological knowledge of this complex network, we use the evolutionist methods for its inception, thus enabling us to obtain, among other things, a modular network. Finally, we present our results:}}
