....These distinct scopes allow both the layout designer and programmer to focus on the specification and application of constraints to the most appropriate context. The Overall Architecture The overall algorithm is based on the constraint engine for multimedia layout developed in LayLab [3] and uses Boolean constraints in the sense of Mackworth [6] for the validation of a given layout situation. The schematic architecture of YPPS is illustrated in fig. 5. The architecture of YPPS is structured according to distinct scope levels. Each of the different levels has its own control ....

....of the layout task would, however, lead to unsatisfactory results. Rather, layout has to be considered as an important carrier of meaning. To determine effective display layouts for the generated multimedia material, constraint based layout techniques have been developed for WIP and PPP (cf. [35, 38]) Here the automatic placement of multimedia layout is viewed as a multidimensional optimization problem that is formalized as constraint satisfaction problem in a finite discrete search space. We have encoded graphical design knowledge via a set of prioritized constraints expressing ....
....constraint satisfaction problem in a finite discrete search space. We have encoded graphical design knowledge via a set of prioritized constraints expressing semantic pragmatic, geometrical topological, and temporal relations. Graf has developed the generic constraint based layout framework LayLab [36, 38], as a first approach towards a principled multimedia layout manager, which incorporates two dedicated constraint solvers including the local propagation solver SIVAS and the finite domain solver FIDOS. SIVAS extends the constraint hierarchy solver DeltaBlue by indirect reference constraints in ....
