New spatio-textual indexing methods are needed to support efficient search and update of the massive amounts spatially referenced text being generated. Location based services using geo-tagged documents provide valuable ranked recommendations about nearby restaurants, services, sales, emergency events, visitor attractions. Consequently, top-k spatial keyword queries (TkSKQ) have received a lot ...

A hybrid algoritm to find the absolute extreme point of a multimodal scalar function of many variables is presented. The algorithm is well suited to be implemeted in parallel over a distributed computer environment. The algorithm is suitable when the objective function is expensive to compute, the computation can be affected by noise and/or partial derivatives cannot be calculated. The method u...

Phylogenetic trees are important in biology since their applications range from determining protein function to understanding the evolution of species. Maximum Likelihood (ML) is a popular optimization criterion in phylogenetics. However, inference of phylogenies with ML is NP-hard. Recursive-Iterative-DCM3 (Rec-I-DCM3) is a divideand-conquer framework that divides a dataset into smaller subset...
