follows:

param$\_$grid

'max$\_$depth': $[5,10,15,20,25],$

'min$\_$samples$\_$split': $10,20,30,40,50,60,70,80,90,100$

$\}$

The first attempt of GridSearchCV$()$ produces the following best parameters: Initial parameters: $\{\text{'}$max$\_$depth': $5,$ 'min$\_$samples$\_$split': $40\}$

How should the person set the second param$\_$grid? Why?
