Algorithmic characteristics

Typical algorithms and data structures textbooks are seven or eight hundred pages long, include chapters about software engineering and the programming language used in the book, and include appendices with yet more information about the programming language. Often they include lengthy case studies with tens of pages of specifications and code. Frequently they are hardcover books printed in two colors; sometimes they have sidebars with various sorts of supplementary material.

We present a CYK and an Earleystyle algorithm for parsing Range Concatenation Grammar (RCG), using the deductive parsing framework. The characteristic property of the Earley parser is that we use a technique of range boundary constraint propagation to compute the yields of nonterminals as late as possible. Experiments show that, compared to previous approaches, the constraint propagation helps to considerably decrease the number of items in the chart.

Attribute grammars are an elegant formalization of the augmented contextfree grammars characteristic of most current natural language systems. This paper presents an extension of Earley's algorithm to Knuth's attribute grammars, considering the case of Sattributed grammars. For this case, we study the conditions on the underlying base grammar under which the extended algorithm may be guaranteed to terminate. Finite partitioning of attribute domains is proposed to guarantee the termination of the algorithm, without the need for any restrictions on the contextfree base. ...

Note immediately one diﬀerence between linear equations and polynomial equations: theorems for linear equations don’t depend on which ﬁeld k you are working over, 1 but those for polynomial equations depend on whether or not k is algebraically closed and (to a lesser extent) whether k has characteristic zero. Since I intend to emphasize the geometry in this course, we will work over algebraically closed ﬁelds for the major part of the course.

The study that led to this report was called for in the President’s Fiscal Year 2006 Budget. In accordance with that call, the study was commissioned by the National Coordination Office (NCO) for Networking and Information Technology Research and Development (NITRD), which supports the NITRD Subcommittee, which operates under the White House National Science and Technology Council to coordinate federal investments in networking and information technology research and development.

An origin of these algorithms is found in the Darwian principles of natural selection (Darwin, 1859). In accordance with these principles, only the ﬁttest individuals can survive in the struggle for existence and reproduce their good characteristics into next generation. As illustrated in Fig. 1, evolutionary algorithms operate with the population of solutions. At ﬁrst, the solution needs to be deﬁned within an evolutionary algorithm. Usually, this deﬁnition cannot be described in the original problemcontext directly....

Similarly, when a problemto be solved froma domain where the problemspeciﬁc knowledge is absent evolutionary algorithms can be successfully applied. Evolutionary algorithms are easy to implement and often provide adequate solutions. An origin of these algorithms is found in the Darwian principles of natural selection (Darwin, 1859).

Recently, several solutions to the robot localisation problem have been proposed in the scientific community. In this chapter we present a localisation of a visual guided quadruped walking robot in a dynamic environment. We investigate the quality of robot localisation and landmark detection, in which robots perform the RoboCup competition (Kitano et al., 1997). The first part presents an algorithm to determine any entity of interest in a global reference frame, where the robot needs to locate landmarks within its surroundings.

Conventional servo systems, to ensure machine performance, smoothness, positional error and low servo noise, require the adjustment of its servo’s gains as an initial crucial step. Even systems that employ autotuning require manual tweaking after the system is installed, especially if more that one axis are interdependent. EziSERVO® employs the best characteristics of stepper and closed loop motion controls and algorithms to eliminate the need of tedious gain tuning required for conventional closed loop servo systems.

Software Component Characteristics This chapter addresses the structure and function of lowlevel software components. These include algorithms, modules (e.g., Ada packages, C++ objects), and APIs. The perspective is bottomup, with the emphasis on computational complexity. Lowlevel algorithms may be simple at first, but complexity can increase over time. The increases in complexity can occur with research advances. Measures taken to compensate for a performance problem in one area (e.g., noisy voice channel) can increase complexity of an algorithm (e.g.
