Qin et al. [11] used the search results of several search engines to diversify the crawling seeds.
Scatter Search uses strategies to diversify and intensify the search in order to avoid local minima and to find quality solutions and, on the opposite to other evolutionary heuristics, it emphasizes systematic processes against random procedures.
Today, companies like Yandex and Google make the bulk of their revenues from search ads, but to diversify, and to offset whatever declines that business may see in the future, they need to continue developing and investing in new areas like this, and so we're likely to see more of this to come.
With public funding no longer to be counted on, universities are searching for ways to diversify their revenue.
We utilise the strength of IP not only to diversify the search process, but also to intensify the search efforts.
This dynamic search space allows the GA to diversify its population with new solutions that are not available with fixed search space.
The pseudocode of our genetic algorithm framework is presented in Algorithm 2. It uses an exhaustive generation approach to diversify the search, a hydrophobic core directed macro-mutation operator to intensify the search, and a random-walk algorithm to recover from stagnation.
Henchiri and Ennigrou (2013) proposed a multiagent model based on a hybridization of two metaheuristics, a local optimization process using the tabu search to get a good exploitation of the good areas and a global optimization process integrating the particle-swarm optimization (PSO) to diversify the search towards unexplored areas.
To diversify the search, we employ a tabu scheme and a penalization strategy, both compatible with the SMD design.
Finally, we also define a notion of result diversity in the setting of RDF data and provide mechanisms to diversify RDF search results using Maximal Marginal Relevance.
