Exploiting temporal coherence in forest dynamics simulation
Understanding the impact of climate and land-use on forest ecosystems involves modeling and simulating complex spatial interactions at many different scales. With this goal in mind, we have developed an individual-based, spatially explicit forest simulator, which incorporates fine-scale processes that influence forest dynamics. In this paper we present new, faster algorithms for computing understory light and for dispersal of seeds | the two most computationally intensive submodules in our simulator. By exploiting temporal coherence, we circumvent the problem of doing the entire simulation at each step. We provide experimental results that support the efficiency and efficacy of our approach. © 2011 ACM.
