"As I read the article, this is a model of the dispersion of a cloud, but unless I missed something, it doesn't account for the half-life of the radioactive particles. Thus, if many of the radioactive particles have a short half-life (which is…"

"One more thought on benchmarks: to get an apples-to-apples comparison, make sure you compare performance with default settings and performance with tuned parameters. The major solvers let you set parameters to improve the performance; a few changes…"

"We're pleased with the public benchmarks, but they should be "taken with a grain of salt". The benchmark that matters most is how well does a solver work on the models that you want to solve, as opposed to a standard academic test…"

"Hi Yi-Chun!
The best option is to look at the alternatives yourself. Figure out which option gives you the right combination of speed, features, price and service. The vendors offer various evaluation copies and benchmarking services that can help…"
