A method of determining an adjustment of a rotary blade, comprising: receiving track and balance performance data for a rotary blade having at least one adjustable track and balance adjustment mechanism; establishing at least one track and balance threshold for the rotary blade; wherein the threshold includes an adjustment threshold comprising a number of adjustments associated with a track and balance adjustment solution for the rotary blade, and wherein the threshold includes a performance threshold comprising an expected performance associated with a track and balance adjustment solution for the rotary blade; defining a track and balance adjustment solution search tree using a branch and bound solution search algorithm; selecting a first track and balance adjustment solution from the search tree for evaluation; evaluating the first track and balance adjustment solution using the adjustment threshold by determining (202; 302) a number of adjustments for the selected first track and balance adjustment solution, and comparing (204; 304) the number of adjustments for the selected first track and balance adjustment solution with the adjustment threshold for the rotary blade; and determining whether to evaluate a second track and balance adjustment solution from the search tree based on the evaluation of the first track and balance adjustment solution; wherein each track and balance adjustment solution corresponds to a different specific configuration of the at least one track and balance adjustment mechanism of the rotary blade, and where each main branch of the search tree corresponds to one track and balance adjustment mechanism and any sub-branch of a main branch requires the addition of another adjustment mechanism, the method including pruning (206; 306) the first track and balance adjustment solution and the second track and balance adjustment solution from the search tree of the branch and bound search algorithm based on the determined number of adjustments and the adjustment threshold comparison, and selecting (214; 314) a third track and balance adjustment solution from the search tree for evaluation. receiving track and balance performance data for a rotary blade having at least one adjustable track and balance adjustment mechanism; establishing at least one track and balance threshold for the rotary blade; wherein the threshold includes an adjustment threshold comprising a number of adjustments associated with a track and balance adjustment solution for the rotary blade, and wherein the threshold includes a performance threshold comprising an expected performance associated with a track and balance adjustment solution for the rotary blade; defining a track and balance adjustment solution search tree using a branch and bound solution search algorithm; selecting a first track and balance adjustment solution from the search tree for evaluation; evaluating the first track and balance adjustment solution using the adjustment threshold by determining (202; 302) a number of adjustments for the selected first track and balance adjustment solution, and comparing (204; 304) the number of adjustments for the selected first track and balance adjustment solution with the adjustment threshold for the rotary blade; and determining whether to evaluate a second track and balance adjustment solution from the search tree based on the evaluation of the first track and balance adjustment solution; wherein each track and balance adjustment solution corresponds to a different specific configuration of the at least one track and balance adjustment mechanism of the rotary blade, and where each main branch of the search tree corresponds to one track and balance adjustment mechanism and any sub-branch of a main branch requires the addition of another adjustment mechanism, the method including pruning (206; 306) the first track and balance adjustment solution and the second track and balance adjustment solution from the search tree of the branch and bound search algorithm based on the determined number of adjustments and the adjustment threshold comparison, and selecting (214; 314) a third track and balance adjustment solution from the search tree for evaluation.
