Yet Another Logo Language
Full text linkIn this paper we propose to enhance standard Logo by introducing modern program paradigms. In particular we extend Logo with object-oriented programming and multi-agent programming features. This new language is called YALL and try to change the way of programming Logo without abandon the original philosophy of the language. We also discuss a possible implementation of YALL using the Java language by Sun Microsystems
Runtime support for self-evolving software
No full textSoftware development and deployment is based on a well established two stage model: program development and program execution. Since the beginning of software development, meta-programming has proven to be useful in several applications. Even though interpreted languages have successfully exploited the ability of generating programs, meta-programming is still far from being main stream. The two stage model is largely due to the computing metaphors adopted for defining programs, and deeply entrenched within the whole software management infrastructure. In this paper we explore how a runtime, multi-staged, self-contained, meta-programming system based on the notion of partial application can provide a suitable support for programs capable of evolve along time. To make the discussion more concrete we discuss two scenarios where the suggested infrastructure is used: software installation and robot control by means of programs embedding knowledge into thier code rather than into data structures
Layered Reactive Planning in the IALP Team
No full textThe main ideas behind the implementation of the IALP RoboCup team are discussed: an agent architecture made of a hierarchy of behaviors, which can be combined to obtain different roles; a memory model which relies of the absolute positions of objects. The team is programmed using ECL, a Common Lisp implementation designed for being embeddable within C based applications. The research goal that we are Pursuing with IALP is twofold: (1) we want to show the flexibility and effectiveness of our agent architecture in the RoboCup domain and (2) we want to test ECL in a real time application
IALP
No full textIALP is a team for the simulation league of the RoboCup initiative [4]. The team is programmed using ECL, a public domain implementation of Common Lisp [1]
Template Metaprogramming an Object Interface to Relational Tables
No full textWe present a general technique to support reflection in C++, exploiting template metaprogramming techniques. The technique is used for building an object interface to relational database tables. By just annotating a class definition with meta information, such as storage attributes or index properties of fields, a programmer can define objects that can be stored, fetched or searched in a database table. A high-performance, full text search engine has been built with this technique
