The most exact rules I can find for 3- or more way conflict is that the attackers lose ships “roughly evenly”.
I’m trying to write a combat calculator that can actually predict the outcome of a multi-way battle in the absence of formal alliances. Does “roughly evenly” mean the defender does dwt damage to each fleet at a time, with leftovers carrying forward? Does the defender intelligently hit the largest fleet first or the smallest first? Or does “evenly” mean one ship at a time?
Let me try to illustrate with an example: D defends with 6 ships, WS 5. A and B attack with 1 ships and 7 ships respectively, WS 6.
Scenario 1: D defends against a single fleet at a time, stupidly.
First, A’s fleet is eliminated because dwt = 6. Then B is reduced to 2 ships.
Then B’s fleet kills 6, leaving 0.
B survives and owns the planet w/2.
Scenario 2: D defends against a single fleet at a time, intelligently.
First, D kills 6 of B’s ships, leaving A w/1 and B w/6.
Then, D dies.
Then, A is assigned defender because they traveled shortest distance.
Then A deals 7 damage to B, eliminating him.
A survives and owns the planet w/1.
This is clearly better for D, since only 1 ship remains when the dust clears.
Scenario 3: Round robin - will still work out differently depending on the order of the round robin.
In many-way-battles it is even more complex because the defender should seek to leave a domino trail of defenders to be knocked down by the survivors, causing the final survivor to have as few ships as possible.
Keen for people’s input, or ideally for Jay’s confirmation of the actual algorithm.
