Assume b=0.05b=0.05b=0.05 is a constant for all iii in the BDT model as we assumed in the video lectures. Calibrate the aia_iai parameters so that the model term-structure matches the market term-structure. Be sure that the final error returned by Solver is at most 10−810^{-8}10−8. (This can be achieved by rerunning Solver multiple times if necessary, starting each time with the solution from the previous call to Solver.
