The environment is developing not only by the actions of the agents, but also as L systems using its developmental rules..In this chapter we deal with eco-colonies working in the weakly parallel derivation mode. We compare the generative power of wea

We show that P colonies with capacity three and two agents using homogeneous programs without checking rules are computationally complete as well as eco-P colonies with two agents and a passive environment and PCol a

Knowing All Optimal Solutions Does Not Help for TSP Reoptimization knowledge help for finding a high-quality solution for a locally modified instance?.We briefly survey the known results about reoptimization and consider a generalization of the model where not only one optimal solution is given, but the set of . optimal solutions for an instance is available for f
