Managed Forest Reserves: Preserving Diversity

Background As part of the Northwest Forest Plan, large areas have been designated on many federal forests in western Oregon to provide critical habitat for plants and animals that are associated with old-growth habitat. Some of the structural characteristics often considered typical of old forests include large-diameter overstory trees, large standing and fallen dead trees, and one or more unde...

L-Cover: Preserving Diversity by Anonymity

To release micro-data tables containing sensitive data, generalization algorithms are usually required for satisfying given privacy properties, such as k-anonymity and l-diversity. It is well accepted that k-anonymity and l-diversity are proposed for different purposes, and the latter is a stronger property than the former. However, this paper uncovers an interesting relationship between these ...

Analysis of Diversity-Preserving Mechanisms for Global Exploration

Maintaining diversity is important for the performance of evolutionary algorithms. Diversity-preserving mechanisms can enhance global exploration of the search space and enable crossover to find dissimilar individuals for recombination. We focus on the global exploration capabilities of mutation-based algorithms. Using a simple bimodal test function and rigorous runtime analyses, we compare wel...

Preserving Diversity In Changing Environments Through Diploidy With Adaptive Dominance

Genetic algorithms have been applied to a diverse eld of problems with promising results. While most of these mainly address stationary problems, there's another group where the problem is dynamic, represented by a changing tness function. These class of problems are characterized mainly by a need for a mechanism to adapt to the change. The best approach depends on the nature of the change in t...

Migration and Replacement Policies for Preserving Diversity in Dynamic Environments

• Star topology also entails high-quality outcomes but quickly gets stagnated. The reason is that the master island receives many migrants from the subordinate islands after some migrations, implying that populations eventually become very similar. This intuitively involves a lack of diversity so that the gain of fitness gets fatally damaged. This phenomenon affects much more strongly to the hu...
