Brazil is responsible for 27% of the world production of soybeans and 7% of maize. Mato Grosso and Para states in Brazil are among the largest producer. The viability to the cultivation of maize (Zea mays) and soybeans (Glycine max), for future climate scenarios (2070-2100, GHG) is evaluated based on crop modeling (DSSAT) forced by observational data and regional climate simulations (HadRM3). The results demonstrated that a substantial reduction in the yield in particular for maize may be expected for ...

Multi-objective reinforcement learning (MORL) involves the use of reinforcement learning techniques to address problems with multiple objectives, conflicting or not. Among the main techniques used to treat this class of problems, we saw that they are limited by some factors, such as the Pareto Front shape and computational cost. This paper proposes a new iterative algorithm based on the single-policy approach, called Q-Managed. We use a hybrid multi-objective optimization (MOO) method that provides ...
