GPTreeO 1.0.0

• Initial CRAN submission.

GPTreeO 1.0.1

• Make it an option to use default DiceKriging parameter bounds by setting gpcontrol$use_default_var_param_bound

GPTreeO 1.1.0

• Add option for continual forgetting by setting cont_forget_max_leaves
• Add option to merge new point with existing point by setting merge_point_dist
• Add verbose argument to control the amount of information the package prints to console
• Perform additional training on the root node to have predictions available earlier
• Allow for the user to set the number of residuals using use_n_residuals in the error_scaler
• Add method to plot the tree structure plot_tree_structure
• Add method to get the leaf_key for a training point get_leaf_key_from_training_point
• Added vignette for basic GPTreeO functionality
• Improve numerical stability of prediction uncertainty
• Fixed bug that set user-specified gp_control$control to an empty list
• Added option to not inherit GP optimization starting point from parent leaf by setting start_gp_opt_from_parent_pars
• Add option to scale the lower and upper bound through bound_scale for the DiceKriging wrapper
• For the DiceKriging wrapper, make local GP parameter choices more stable by reducing default bound_scale to 10 (was 100)
• Minor code simplifications and efficiency improvements
