Hybrid ant colony optimization in solving multi-skill resource-constrained project scheduling problem

Abstract: In this paper, hybrid ant colony optimization (HAntCO) approach in solving multi-skill resource-constrained project scheduling problem (MS-RCPSP) has been presented. We have proposed hybrid approach that links classical heuristic priority rules for project scheduling with ant colony optimization (ACO). Furthermore, a novel approach for updating pheromone value has been proposed based on both the best and worst solutions stored by ants. The objective of this paper is to research the usability and robustness of ACO and its hybrids with priority rules in solving MS-RCPSP. Experiments have been performed using artificially created dataset instances based on real-world ones. We published those instances that can be used as a benchmark. Presented results show that ACO-based hybrid method is an efficient approach. More directed search process by hybrids makes this approach more stable and provides mostly better results than classical ACO.

EMYS—Emotive Head of a Social Robot

Abstract: This paper presents the design, control, and emotion expressions capabilities of the robotic head EMYS. The concept of motion control system based on FACS theory is proposed. On the basis of this control system six basics emotions are designed for EMYS head. The proposed head shapes are verified in experiments with participation of children aged 8–12. The results of the experiments, perception of the proposed design, and control system are discussed.
