We present and discuss philosophy and methodology of chaotic evolution that is theoretically supported by chaos theory. We introduce four chaotic systems, that is, logistic map, tent map, Gaussian map, and Hénon map, in a well-designed chaotic evolution algorithm framework to implement several chaotic evolution (CE) algorithms. By comparing our previous proposed CE algorithm with logistic map a...

Particle-based simulation methods are gaining popularity for creating animations of physical phenomena such as fluids and melting solids. Extracting and visualizing an explicit surface corresponding to the volume of particles is however a difficult and time-consuming task, especially with increasing particle set sizes. In this paper, we present a novel interactive rendering algorithm for raster...

We present an efficient algorithm for computation of surface representations enabling interactive visualization of large dynamic particle data sets. Our method is based on a GPU-accelerated data-parallel algorithm for computing a volumetric density map from Gaussian weighted particles. The algorithm extracts an isovalue surface from the computed density map, using fast GPU-accelerated Marching ...

This paper describes Synthbee, an assistive tool for sound design which enables musicians to achieve desired sounds without managing parameters of a sound synthesizer manually. The system allows musicians to specify desired sound characteristics using attributes and explore the space of producible sounds by controlling the interactive evolutionary algorithm extended to take into account specifi...

We present a new parallel occlusion culling algorithm for interactive display of large environments. It uses a cluster of three graphics processing units (GPUs) to compute an occlusion representation, cull away occluded objects and render the visible primitives. Moreover, our parallel architecture reverses the role of two of the GPUs between successive frames to lower the communication overhead...

Abstra t. Numeri string is a sequen e of symbols from an alphabet U, where U is some numeri al universe losed under addition and subtra tion. Given two numeri strings A = a 1 a m and B = b 1 b n and a distan e fun tion d(A;B) that gives the s ore of the best (partial) mat hing of A and B, the transposition invariant distan e is min t2U fd(A + t; B)g, where A + t = (a 1 + t)(a 2 + t) : : : (a m ...

This article deals with a usage of artificial intelligent techniques in humanoid robotics. The focus is on social robotics and how to improve the interaction between human and robot. We used the interactive evolution for robotic dance system. In this work the definition, principles and basic features of Interactive Evolutionary Computation are described. This technique optimizes systems based o...

Sensemaking of large graphs, specifically those with millions of nodes, is a crucial task in many fields. Automatic graph layout algorithms, augmented with real-time human-in-the-loop interaction, can potentially support sensemaking of large graphs. However, designing interactive algorithms to achieve this is challenging. In this paper, we tackle the scalability problem of interactive layout of...

| We explore the concept of development without programming by children. Especially, we look at the case of developing robot control systems. The evolutionary robotics approach has shown that in some cases, given a mathematically described tness function, it is possible to achieve an automatic development of robot controllers. However, it is questionable how one is to construct the mathematical...

OBJECTIVE To compare 4 analytic algorithms for interpretation of the Swedish Interactive Threshold Algorithm. INTRODUCTION Analytic algorithms were initially developed for interpretation of standard automated perimetry (using a full threshold strategy). The Swedish interactive threshold algorithm is a novel strategy that was developed to shorten test duration. METHODS One hundred forty-thre...
