This mathematics book relates integer (diphontane) equations to algebraic equations, difference equations to differential equations, and analog elecronics to digital electronics. It is currently being republished and will hopefully be available in 2022.
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.
