Abstract: A method for calculating total organic carbon (TOC) for a sample location includes obtaining an intact core soil sample from a sample location, the core soil sample having a depth and mass; transferring a predetermined fixed mass M from the intact core soil sample into an analysis sample container to obtain an analysis sample; and providing a subsample of the analysis sample for soil organic carbon (SOC) concentration testing.

Abstract: A request is received from a user compute device to solve an optimization problem. A set of subpopulations is identified from an identified population included in the optimization problem. Each subpopulation from the set of subpopulations is associated with a unique sub-machine resource from a set of sub-machine resources at a set of remote compute devices. Each sub-machine resource is caused to determine an associated set of candidates from an associated subpopulation from the set of subpopulations and for that sub-machine resource. Each sub-machine resource is caused to generate an associated set of offspring based on an objective function associated with the associated set of candidates for that sub-machine resource. Each sub-machine resource is caused to mutate the associated set of offspring to generate an associated set of mutated offspring. An updated population is determined, and a representation of a response is determined based on the updated population.
