1. Introduction
---------------
NoNoCAB is a forked version of NoCAB which fixes the most annoying bugs and crashes
of the OpenTTD AI NoCAB. NoCAB is in general a very well performing AI but it
has some problems which have made it less fun to use.

Since there hasn't been any progress in a while I decided to see if I could do
something about the biggest problems especially the crashing while saving.
Besides that lots of other problems have been fixed and improvements have been made.

The idea behind this ai and it's precursor NoCAB is to predict the profits of a
connection (route, cargo, vehicle combination) and build the ones that it thinks
are the most profitable.


2. Bug reporting and other links
--------------------------------
I am not aware of any crashes still appearing but please report any
problems that you encounter in NoNoCAB's forum topic listed below.
Remarks aboput possible improvements or non optimal handling of
certain situations are also welcome.

3. Requirements
---------------
NoNoCAB uses the AI library Queue.BinaryHeap (version 1).
Minimum OpenTTD version: 1.2.


4. Limitations
--------------
NoNoCAB generally prefers building longer (train, road vehicle) routes.
As such it will use a lot of infrastructure which means it may have
problems when infrastructure maintenance is on. In this case it is
advisable to disable aircraft for NoNoCAB (or all ais) or at the
very least set the plane speed factor to 1/1 instead of the default 1/4.
It does not have any special handling for industry NewGRFs, In general
this usually doesn't cause too many problems but certain industry
types may be handled non optimal.
There is no support for goal scripts meaning NoNoCAB will try to do its
normal thing without consideration for any possible goals.
When NoNoCAB has a lot of connections, especially long ones (trains),
then it can run out of time when saving the game. It tries to detect
that, because it would crash when its alloted saving times is up.
If it detects that time is almost up it will stop saving its
connections and prefere those connections to be lost to crashing.
When loading a save game where that happened, it won't be able to
load the connections that did not get saved. Instead it will since
version 7 send all vehicles without a saved connection to depot and
sell them eventually. After that stations without a saved connection
where no vehicles are left will be removed. Note that roads, rail
tracks and depots are not removed in that case. If you are playing
with infrastructure costs enabled, this will affect NoNoCAB
negatively.
