A market model for level of detail control

J. Howell, Y. Chrysanthou, A. Steed, M. Slater
1999 Proceedings of the ACM symposium on Virtual reality software and technology - VRST '99  
One of the techniques for controlling the frame rate is the assignment of different levels of detail for each object within a scene.  ...  We propose an algorithm based on an analogy to a market system where each object does not have an assigned level of detail but has the ownership of a certain amount of time which it can use to be rendered  ...  THE MARKET MODEL CONCEPT 3.1 The Market model The inspiration for the new level of detail control algorithm was that of the concept of a trading market.  ...

The measure- ment problem is more easily comprehended at such a detailed level than for market aggregates. Simi- larly, greater control can frequently be exercised at this lower aggregate level.  ...  It appears likely, however, that a marketing model that captures the essence of the advertising influence process will be much more complex, requiring more detailed input data, than the models now being  ... 

Speculative housing markets and rent control: insights from nonlinear economic dynamics

Noemi Schmitt, Frank Westerhoff
2021 Journal of Economic Interaction and Coordination  
AbstractWe propose a novel housing market model to explore the effectiveness of rent control.  ...  We show that policymakers may use rent control to reduce the rent level, although such policies may have undesirable effects on the house price and the housing stock.  ...  To view a copy of this licence, visit http://creat iveco mmons .org/licen ses/by/4.0/.  ...
