State-space search methods in problem solving have often been illustrated using tree diagrams. We explore a set of issues related to coordination in collaborative problem solving a...
Diagrammatic logics have advantages over symbolic cousins. Peirce thought that logical diagrams (Existential Graphs, EG) are capable of "expression of all assertions", as...
Research on effective algorithms for efficient graph layout continues apace, and faster technology has led to increasing research on algorithms for the depiction of dynamic graphs ...
Abstract. This paper explores factors associated with effective external representation (ER) use. We describe an information-processing approach to the assessment of ER knowledge. ...
Visualizations of space, time, and agents (or objects) are ubiquitous in science, business, and everyday life, from weather maps to scheduling meetings. Effective communications, i...
Abstract. We review the use of diagrams in the UK National School Curriculum (NC) and assess it in the light of current research on childrens' graph comprehension. It is noted...
In the context of artificial intelligence, the multiagent systems are an alternative solution to address complex problems and distributed. PAINALLI is an multi-agent architecture f...
