Optimality modeling
Weboptimality and quantitative genetic models of pheno-typic selection. These models predict simply that a plant should evolve increased specialization for a particular pollinator when … Web2. The Adaptive-Landscape and Semantic Views of Optimality Models. 2.1 We need to describe the structure of optimality models more precisely than we have so far. In particular, we need to differentiate the two main components of every optimality model: 1) the design problem to be solved, and 2) the set of feasible solutions under consideration.

Unfortunately, most existing optimality-based models only consider vertical vegetation-soil-water interactions on plot scale, without considering the lateral hydrological processes. …
WebJan 18, 2024 · The optimality model of leaf longevity (LL: day) proposed by Kikuzawa rests on two assumptions. First, daily photosynthesis declines linearly from an initial maximum (denoted by A 0, g biomass m −2 day −1) with increasing age. Second, LL maximizes the leaf’s lifetime-average net carbon gain (accumulated daily photosynthesis averaged over ...

WebThe optimality criterion used in generating D-optimal designs is one of maximizing X'X , the determinant of the information matrix X'X. This optimality criterion results in minimizing the generalized variance of the parameter estimates for a pre-specified model. As a result, the 'optimality' of a given D-optimal design is model dependent.
