Ah, but Raimar has got a point.
The current explorer mode is very bad at uncovering tiles for city
settling. It is, however, rather good at finding enemies. Those, I think,
are the two only modes of exploration that are needed.
Of course, then there is scooping up huts and empty cities, but that is
something common to both modes.
We will want client-side autoexplorers, which means moving it into
client/ai/common/. This shouldn't present a big problem once the new
pathfinding interface is in. User clients should use the old mode always,
as this works fine as is.

Hah. It is not easy.
Yes, in order to use the "explore greatest possible compact area" mode
(for settling) you need a reference point. As opposed to the "explore the
greatest possible amount of space" mode (for finding your enemy).
But, you will need to look at the terrain to avoid walking needlessly over
mountains when you could save a lot of time going around. That's one
warmap (or whatever you guys call it now). It is also needed for hut and
empty city finding.
Then you need to keep in mind that what we are really concerned with here,
isn't the number of tiles from your reference point and to the fogged
tile, but the move cost for your settler to go somewhere. So it makes a
lot less sense to explore a huge mountain range than to explore flat land
or follow rivers. So you need another warmap from the reference point and
The best tile to explore is then something like (cost of warmap1)+(cost of
Now, the case is quite different when it comes to sea exploration. Since
the ocean is topographically flat, we don't need a warmap there, for
either mode. In the first mode, we should circle the continent. In the
second, we should just do as we do now. So we may want to separate the
land and ocean autoexploration functions, since they have very different
I did start rewriting the existing autoexplore in this direction, but
didn't get too far, partly because you can't overlap two warmaps in the
