Solving large nonconvex water resources management models using generalized benders decomposition by Cai, Ximing, McKinney, Daene C., Lasdon, L. S., Watkins, D.

“…In this paper, we apply the Generalized Benders Decomposition (GBD) algorithm to two large nonconvex water resources models involving reservoir operations and water allocation in a river basin, using an approximation to the GBD cuts proposed by Floudas et al. (1989) and Floudas (1995). …”

Joint mapping of quantitative trait loci for multiple binary characters by Xu, Chenwu, Li, Zhikang, Xu, Shizhong

“…We treat the multivariate liabilities as missing values so that an expectation-maximization (EM) algorithm can be applied here. We also extend the method to joint mapping for both discrete and continuous traits. …”

T cell epitope identification for bovine vaccines: An epitope mapping method for BoLA A-11 by Groot, A.S., Nene, Vishvanath M., Hegde, N.R., Srikumaran, S., Rayner , J., Martin, W.

“…Similar tools are not yet available for predicting T cell epitopes for animal vaccines, but there may be sufficient data available to begin the process of compiling the algorithms. We describe the construction of a novel mathematical `matrix' that describes the properties of bovine major histocompatibility complex (BoLA) system antigen (BoLA) A-11 peptide ligands, developed for use with EpiMatrix, an existing T cell epitope-mapping algorithm. …”

Fourier analysis of historical NOAA time series data to estimate bimodal agriculture by Canisius, F., Turral, Hugh, David, S.

“…This result indicates that estimating bimodal agriculture area that is one of the main sources of information for irrigated area mapping at regional or global scale, with improved accuracy possible if greater spatial, temporal resolution is achieved, for instance from MODIS or SPOT vegetation time series NDVI data, combined with (1) an improved decision tree classification algorithm and (2) a greater precision and geographical distribution of ground-truth data. …”

Wrapper for building classification models using Covering Arrays by Dorado, Hugo Andres, Cobos, Carlos, Torres Jimenez, Jose, Burra, Dharani Dhar, Mendoza, Martha, Jiménez, Daniel

“…This lack of accuracy, by which the new wrapper fails to match PSO, is offset by the fact that the user does not need to fine tune algorithm parameters, such as velocity ranges, timing, cognitive coefficient, and social coefficient, while it is also much easier to program in parallel.…”

Horizon scanning to assess the bioclimatic potential for the alien species Spodoptera eridania and its parasitoids after pest detection in west and central Africa by Tepa-Yotto, Ghislain T., Gouwakinnou, G.N., Fagbohoun, J.R., Tamo, Manuele, Saethre, M.

“…The current work was carried out to predict the potential spatial distribution of SAW and four of its co-evolved parasitoids at a global scale using the maximum entropy (Maxent) algorithm. RESULTS SAW may not be a huge problem outside its native range (the Americas) for the time being, but may compromise crop yields in specific hotspots in coming years. …”
