WebAbstract – The accuracy of the hybrid method is validated by showing that the computed solutions of three trees are in good agreement with those solved from FEKO. Next the hybrid method is used for Monte Carlo simulations of forest stands with up to 30 trees. The dependences of the solutions on tree heights and tree densities are illustrated. WebDec 28, 2024 · Limitations. The results of GridSearchCV can be somewhat misleading the first time around. The best combination of parameters found is more of a conditional “best” combination. This is due to the fact that the search can only test the parameters that you fed into param_grid.There could be a combination of parameters that further improves the … WebThe wire-grid method, adopted in our study to model the buildings, has also been used by other researchers , albeit in conjunction with the MoM.
