This paper advocates the use of methods based on global approximation models for optimization problems with time-consuming function evaluations and integer variables.We show that methods based on local approximations may lead to the integer rounding of the optimal solution of the continuous...

The research that studies the interaction between sequencing situations and cooperative games, that started with the paper of Curiel et al. (1989), has become an established line of research. This paper introduces a new model in this field: partitioning sequencing situations and games. The...

The interaction between sequencing situations and cooperative games starting from the paper of Curiel et al. [Curiel, I., Pederzoli, G., Tijs S., 1989. Sequencing games. European Journal of Operational Research 40, 344-351], has become an established line of research within the theory of...

Fertilizer use remains below recommended rates in most of Sub-Saharan Africa, contributing to poor crop yields and poverty. Farmers voice suspicion that available fertilizer is often adulterated, but these concerns are not backed by reliable evidence. In fact, an insight from industry but absent...

At the onset of the United Nations' decade of ecosystem restoration, lessons from well-designed impact evaluations on land restoration programs are crucial for improving policymaking. This study presents findings from a systematic review of research on the socioeconomic impact of such...
