Operator-splitting appears to be an accurate approach, provided that the solution is iteratively improved at each time-step.
In the proposed weighted interference minimization, the SINR of the weakest UT is iteratively improved, in addition to the interference minimization.
In the second stage, the underlying guide-tree is iteratively improved, yielding a new progressive alignment.
Each TS run is started from a random structure which is iteratively improved as described in section Heuristics.
K-means [ 23, 25- 27] is a standard partitioning clustering method based on K centroids of a random initial partition which is iteratively improved.
In co-training [which belongs to a larger class of semi-supervised learning methods (Chapelle et al., 2006)], two models are iteratively improved by continuously increasing the training (labeled) set at each iteration based on the agreement of the models on the unlabeled examples.
These computational coordinates can be iteratively improved and incorporated in MS assay libraries and re-used in future experiments.
According to the actual strength of pseudospecies boundaries the lumped model can be iteratively improved.
For modeling purposes, we generated a binary code for each mammal and bird species (1, if the species is currently known to host any flavivirus and 0, if not, Supplementary Data file 3), generating a baseline for prediction based on known species, which will be iteratively improved following the discovery of new flaviviruses hosts with appropriate field data.
The simple analytical methodology presented in this paper can provide a good initial guess for an optimal geometry to be iteratively improved and refined using more advanced codes and methods.
Ecosystem-based monitoring should be dynamic/adaptive in the sense that models and monitoring designs are iteratively improved by new empirical results, new technologies and the evolving needs of stakeholders.
