Utilitas Mathematica 52 ( 1997 ), pp 123 - 128
This concerns mathematical methods involving the calculus of variations on how to expend a resource over time.
This is a supplement to the above paper on optimal consumption. It also gives a worked example done with the simulation program below.
Concerns how to spend a fixed amount of resources for optimal utility over a fixed amount of time and known interest rate. Based on the above paper.
Wavelets are powerful approximating functions. Here they are applied to the MEI ( Measured Equation of Invariance ) method and some various optimal control problems for improved computational speed and quicker convergence to a solution.
