– Agents dont concern any information about external modules – Agents initialize interactions with each other via Agents Server (and may continue the interaction directly for optimization) – Agents may use any module which has exported its interface to Language Linker – Agents are composed from orthogonal projections to a subset of system modules at current system state A GENTS P ROPERTIES M ULTI -A GENT S YSTEMS Physical Engine Agents Server Агент Agent Language Linker Агент Other Modules

L ANGUAGE S UBSYSTEM – Language subsystem translates the sources to byte-code and allows to execute and debug this code on virtual machines provided by language support modules – The subsystem is designed to work with any set of programming languages – Language linker is responsible for interaction of portions of code written in different languages and executed on different virtual machines – It is possible to use few languages to develop one agent or module – Currently, the modules for Smalltalk, Elendor-C++ (a subset of C++) and Console scripting language (ECSL) is provided Language Linker (inter-language gate) Agents Server Execution Controller Translators Debuggers Virtual Machines LANGUAGE SUPPORT MODULES
