Any of this useful in KSP?

I found a scientific paper talking about how to calculate the most fuel efficient descents to Mars, https://behcet.ae.utexas.edu/sites/default/files/comparison_aiaa.pdf, would any of that be useful to our landers if we wanted to have a very tight delta-v budget? The maths in it is pretty complex, with matrices and stuff that's far ahead of my level though.

The techniques are applicable, though you'd probably need something like KER to get your initial parameters.
