Comparative analyses of covariance matrix adaptation and iterative ensemble smoother on high-dimensional inverse problems in high-resolution groundwater modeling

•Both CMA-ES and the ES-LM perform well for low dimensionality of unknown parameters.•ES-LM can underestimate uncertainty with small ensemble size.•CMA-ES is more computational demanding than ES-LM for high-dimensionality problems.•ES-LM outperforms the CMA-ES in calibrating high-resolution groundwa...
