Early chapter 4 investments are a nightmare for people who, like me, ask themselves too many questions. Once you've bought the obvious ones (Givini Orc Merchant, Givini and Stineford Banks etc.), you're still left with a bunch of money and a long list of investments. And, while you want to buy most of them eventually, deciding which one to prioritize can quickly devolve in analysis paralysis, with numerous possibilities roughly equivalent at first glance but slightly better or worst in practice.
So I've coded a small tool that brings in the big mathematical guns to compute the "best" (biggest returns, lowest cost) investments for a given strategy:
It's very much an advanced tool, intended to be used as a complement to the Calculator, and basically useless without it. As of now, only the first two rounds are coded, and I'm definitely taking a (long) break before giving a try at the third one (the one with the Council of Gawnfall in the middle of it). Still quite helpful in its current form I would say (it did find an investment route I had missed for my save/strategy, so that's at least one person it helped).
Important note: As of now, the algorithm, while not really doing 2N computations (see https://github.com/Rachnera/tls-investment-advisor#algorithm if you're curious) still does a lot. No brilliant idea on how to improve upon that in the generic case yet, open to suggestions. If this takes too much time on your computer, explicitly forcing a few investments (the Givini Orc Merchant and the Bank of Givini for example) should improve things tremendously.
