The key of automatic change detection between multi-temporal images is these images' matching accuracy should reach sub-pixel level. Nevertheless, due to the influence of various factors of geometrical distortion, remote sensing images after precise geometrical correction always still have pixel-level geometrical distortion. Therefore, ideal result of automatic change detection can't be achieved by these images directly. This paper proposes a new automatic change detection approach based on least square image matching. Using least square method to correct images' distortion, we get the Maximum correlation coefficient by iteration and obtain the optimal match point. By correlation coefficient, whether change or not can also be estimated. This approach resolves the multi-temporal image matching accuracy's influence to the change detection result, by which the accuracy of automatic change detection is guaranteed. The experiment results are provided, which indicate the effectiveness and the reliability of the approach.

The language in which evolving programs are expressed can have significant impacts on the problem-solving capabilities of a genetic programming system. These impacts stem both from the absolute computational power of the languages that are used, as elucidated by formal language theory, and from the ease with which various computational structures can be produced by random code generation and by the action of genetic operators. Highly expressive languages can facilitate the evolution of programs for any computable function using, when appropriate, multiple data types, evolved subroutines, evolved control structures, evolved data structures, and evolved modular program and data architectures. In some cases expressive languages can even support the evolution of programs that express methods for their own reproduction and variation (and hence for the evolution of their offspring).This tutorial will begin with a comparative survey of approaches to the evolution of programs in expressive programming languages ranging from machine code to graphical and grammatical representations. Within this context it will then provide a detailed introduction to the Push programming language, which was designed specifically for expressiveness and specifically for use in genetic programming systems. Push programs are syntactically unconstrained but can nonetheless make use of multiple data types and express arbitrary control structures, supporting the evolution of complex, modular programs in a particularly simple and flexible way. The Push language will be described and demonstrated, and ten years of Push-based research, including the production of human-competitive results, will be briefly surveyed. The tutorial will conclude with a discussion of recent enhancements to Push that are intended to support the evolution of complex and robust software systems.

This paper presents an autonomic system in which two managers with different responsibilities collaborate to achieve an overall objective. The first, a node group manager, uses modeling and optimization algorithms to allocate server processes and individual requests among a set of server machines grouped into node groups, and also estimates its ability to fulfill its service-level objectives as a function of the number of server machines available in each node group. The second, a provisioning manager, consumes these estimates from one or more node group managers, and uses them to allocate machines to node groups over a longer timescale. We describe the operation of both managers and the information that flows between them, and present the results of a simple experiment demonstrating the effectiveness of our technique. Furthermore, we relate our architecture to a general autonomic computing architecture based on self-managing resources and patterns of inter-resource collaboration. We also discuss some of the issues involved in incorporating our implementation into existing products in the short term, and describe a number of further directions for this research.
