MWH Soft Releases InfoWater Valve Criticality Modeling (VCM)

Web wire reports that MWH Soft released "first-of-its-kind InfoWater VCM, The Ultimate Solution for Infrastructure Criticality and Vulnerability Assessment". The software contains a genetic algorithm as one of its components:

Built atop ArcGIS (ESRI, Redlands, CA) and drawing on the most advanced numerical computation and genetic algorithms optimization technologies, Infowater effortlessly reads GIS datasets; corrects network topology problems and data flaws; extracts pertinent modeling information; and automatically constructs, skeletonizes, loads, calibrates and generates optimized design, rehabilitation and pump scheduling solutions with astounding speed.

GECCO lineup looks good

The preliminary schedule for the GECCO conference (Genetic and Evolutionary Computation Conference) is posted here and it looks like another winner. Even years are typically slow ones, but conference registration is ahead of plans and it looks as though attendance will keep pace with recent conferences. More information about registration can be found here.

Bioinformatics package uses GAs

Bruker Daltonics ClinProTools 2.1 uses genetic algorithms and other techniques for biomarker panel analysis, biofluid profiling, multivariate data analysis of large sample cohorts, classical statistics and sample classification (see here):

ClinProTools 2.1 now includes many additional features for data analysis and visualization: the new proprietary Supervised Neural Network(TM) algorithm allows a third independent multiclass, multivariate analysis approach, complementing the company's existing Support Vector Machine and Modified Genetic Algorithm. Furthermore, it supports univariate peak statistics and a proprietary QuickClassifier (TM) algorithm. In addition to these supervised approaches, ClinProTools 2.1 also includes Principle Component Analysis (PCA) for unsupervised data analysis.

More information is available at the company's web site (here).
