On the quantum cohomology of the plane, old and new Z. Ran Abstract We describe a method for counting maps of curves of given genus (and variable moduli) to P 2 , essentially by splitting the P 2 in two; then specialising to the case of genus 0 we show that the method of quantum cohomology may be viewed as the 'mirror' of the former method where one splits the P 1 rather than the P 2 , and we i...

To solve the problems that whale optimization algorithm is easy to fall into local and slow convergence speed, improved proposed. Firstly, uses Skew Tent chaotic map initialize population, improve diversity of original population make individual position distribution whales more uniform; Secondly, nonlinear factor based on inverse incomplete ? function used balance global exploration developmen...

This paper presents a strategy for achieving practical mapping navigation using a wheeled mobile robot equipped with an advanced sonar sensor. The original mapping navigation experiment, carried out with the same robot configuration, builds a feature map consisting of commonplace indoor landmarks crucial for localisation, namely planes, corners and edges. The map exhaustively maintains covarian...

We describe a search-based map generator for the classic real-time strategy game Dune 2. The generator is capable of creating playable maps in seconds, which can be used with a partial recreation of Dune 2 that has been implemented using the Strategy Game Description Language. Map genotypes are represented as low-resolution matrices, which are then converted to higher-resolution maps through a ...
