An examination of daily CO emissions prediction through a comparative analysis of machine learning, deep learning, and statistical models.

Human-induced global warming, primarily attributed to the rise in atmospheric CO, poses a substantial risk to the survival of humanity.

Surrogate-assisted global and distributed local collaborative optimization algorithm for expensive constrained optimization problems.

This paper presents a surrogate-assisted global and distributed local collaborative optimization (SGDLCO) algorithm for expensive constrained optimization problems where two surrogate optimization phases are executed collaboratively at each generation. As the complexity of optimization problems and the cost of solutions increase in practical applications, how to efficiently solve expensive constrained optimization problems with limited computational resources has become an important area of research. Traditional optimization algorithms often struggle to balance the efficiency of global and local searches, especially when dealing with high-dimensional and complex constraint conditions.
