Empirical experience shows that human experts determine suitable hybrids to
grow in four steps. A general expert system prototype is built on the same
principle, using an agent-oriented approach. The knowledge base consists o
f several agents. Agents communicate using their own language and update th
eir internal beliefs until a solution is reached. A general prototype is be
ing used for the creation of an expert system prototype fbr the determinati
on of optimal maize hybrids to grow. (C) 2000 Elsevier Science B.V. All rig
