LuDiAI AfterFix
===============

LuDiAI AfterFix is an AI that builds road, air, ship and rail routes
transporting either mail or passengers.

It's an AI that is built upon the original work of lukin_'s LuDiAI.
Initial work was on fixing issues found on the original, but it became
something more of its own later on.

Configuration Settings
----------------------

Town Cargo:
    Choses which cargo the AI will handle.

    - Passengers:
    The AI creates Passenger only routes via road, air, water and/or rail.

    - Mail:
    The AI creates Mail only routes via road, air, water and/or rail.

    - Passengers and Mail:
    The AI creates both Passenger and Mail routes via road, air, water
    and/or rail.


Randomize Town Choices:
    Defines how the AI will pair two towns. When enabled, the AI choses
    the towns at random when creating a service. When disalbed, the AI
    choses the most productive towns first when creating a service.


Is friendly:
    When enabled, the AI tries to avoid building its stations near
    stations of other companies. When disabled, it is allowed to do so.


Can station spread:
    When enabled, the AI expands its road stations by distantly joining
    new station pieces, to enlarge station coverage. It may also join road
    stations with airports, docks, railway stations and vice-versa
    whenever possible.


Rail support:
    Enables or disables the usage of rail routes.


Road support:
    Enables or disables the usage of road routes.


Water support:
    Enables or disables the usage of water routes.


Air support:
    Enables or disables the usage of air routes.


Days dedicated to exclusively attempting a transport mode:
    Time limit for exclusive focus on getting a route of a transport
    type built before allowing the next transport type.


Rail pathfinder profile:
    Select the behaviour of the pathfinder when connecting two towns by
    rails.

    - SingleRail:
    Tweaked for constrained terrain. Connects each of the two lanes
    separately. Tends to succeed more often than the other methods, but
    requires pathfinding twice, one per lane.

    - DoubleRail:
    Tweaked for looks. Connects both lanes in a single instance.

    - RailRedux:
    Tweaked for performance. Connects each of the two lanes separately.


Road pathfinder profile:
    Select the behaviour of the pathfinder when connecting two towns by
    roads.

    - Custom:
    Tweaked for low construction costs when the AI is poor, by avoiding
    watered coast tiles, which may result in some weird bridges across
    two coasts. May try to avoid going through drivethrough stations.
    May build more bridges or tunnels in difficult terrain, especially
    when the slopes are too steep. If the AI is rich, it may build really
    long bridges and tunnels. Relatively slow, but overall, the better
    planner.

    - Default:
    Though the pathfinder interval cost values have been reworked and some
    of the logic regarding bridges and how are roads connected to each
    other, the default profile tries to mimic the behaviour of the
    original LuDiAI pathfinder. It is not cost conscious regarding coasts,
    slopes or bridges, doesn't avoid drivethrough stations and does not
    build too long bridges or tunnels.

    - Fastest:
    Optimized for fastest planning speed, at the cost of low road reuse.
    It prefers fewer curves, which could result in roads going through
    sharp landscapes, or be longer than necessary. Can only build small
    bridges, which may not be ideal for maps with lots of water.


Rail route load orders mode:
    Determines how trains set up their orders.

    - Full load before departing:
    The vehicles will use 'Full load any cargo' on their go-to orders.

    - May load nothing before departing:
    The default 'Load if available' is used on their go-to orders.


Road route load orders mode:
    Determines how road vehicles set up their orders.

    - Full load before departing:
    The vehicles will use 'Full load any cargo' on their go-to orders.

    - Load something before departing:
    A conditional order is placed between their go-to orders that Jump to
    their respective go-to order when load percentage is equal to zero.

    - May load nothing before departing:
    The default 'Load if available' is used on their go-to orders.


Water route load orders mode:
    Determines how ships set up their orders.

    - Full load before departing:
    The vehicles will use 'Full load any cargo' on their go-to orders.

    - Load something before departing:
    A conditional order is placed between their go-to orders that Jump to
    their respective go-to order when load percentage is equal to zero.

    - May load nothing before departing:
    The default 'Load if available' is used on their go-to orders.


Air route load orders mode:
    Determines how aircraft set up their orders.

    - Full load before departing:
    The vehicles will use 'Full load any cargo' on their go-to orders.

    - May load nothing before departing:
    The default 'Load if available' is used on their go-to orders.


Build company statues in towns:
    When enabled, the AI will build statues in honour of its company,
    providing a permanent boost to station rating in those towns.


Run advertising campaigns in towns:
    When enabled, the AI will run advertising campaigns in towns,
    providing a temporary boost to stations with low rating and cargo
    waiting in a small, medium or large radius around the town center.
    When used with "Build company statues in towns", it will prioritize
    the building of statues over advertising campaigns.


Fund construction of new buildings in towns:
    When enabled, the AI will fund the construction of new buildings in
    the smaller towns it services, providing a temporary boost to town
    growth. When used with "Build company statues in towns", it will
    prioritize the building of statues over funding construction.


Buy exclusive transport rights in towns:
    When enabled, the AI will buy exclusive transport rights in towns it
    services. For 12 months, their local authorities will not allow cargo
    to be used by competitors' stations.



Bribe towns to abort competitors' exclusive transport rights:
    When enabled, the AI will bribe local authorities to abort exclusive
    exclusive transport rights of competitors, at the risk of beight
    caught.


Found towns:
    When enabled, the AI will sponsor the construction of new towns in the
    map.


Build headquarters:
    When enabled, the AI will build a company headquarters randomly in the
    map, as cost efficient as possible.
