Norway setup AI

Norway Forces
4-4 MTN, 2-4 Ski DIV, RES 3-3 MIL, 8 Naval units

Norway have four basic setups:
* Capital defence: Is just as the name suggests a setup where the all Norwegian
land forces is setup on Oslo.

* Narvik defence: Is just as the name suggests a setup where all the Norwegian
land forces are setup on or around Narvik, leaving the capital empty.

* Balanced defence: The Norwegian land forces are setup on Oslo and on Narvik, trying to defend both locations.

* Southern costal defence: The Norwegian land forces are setup on or close the cost guarding against an Invasion from the North Sea or Baltic sea.

Declaration of war
Given a CW declaration of war with or without FR/US/USSR and German control of Norway or a GE declaration of war with or without IT and CW control of Norway suggested reasoning for the AI could be as below.

Threats to guard against:
* Threat of paradrop close to Oslo
* Threat of paradrop close to Narvik
* Threat of invasion close to Oslo
* Threat of invasion close to Narvik
* Threat of invasion from North sea
* Threat of a land advance toward Oslo from Sweden
* Threat of a land advance toward Narvik from Sweden/Finland

Good hopes:
* Chance of intervention from controlling power in Narvik
* Chance of intervention from controlling power in Oslo

Threat of paradrop close to Oslo:

IF the Weather is Storm or Blizzard the no risk of paradrop

IF any of the countries at war has a:

Organized ATR AND
it’s in supply or can be put in supply AND
the ATR has range to Olso or can be put in range of it AND
there is a organized PARA AND
it’s in supply or can be put in supply AND
the PARA has range to ATR or can be put in range of it AND
the PARA and the ATR belongs to countries that can cooperate AND
the chance of a successful paradrop is > 20 %

THEN

There is threat of a paradrop close to Oslo

Threat of paradrop close to Narvik:
Same as Threat of a paradrop close to Oslo, but range to Narvik

Threat of invasion close to Oslo

IF the Weather is not Fine or Rain then there is no risk of invasion

IF any of the countries at war has a:

Organized TRS/AMPH/SCS AND one of A or B

A)
it’s in supply or can be put in supply AND
it has range to Baltic Sea the AND
there is a organized LandUnit AND
the LandUnit it’s in supply or can be put in supply AND
the LandUnit and the transporting unit can cooperate AND
the transporting unit can transport the LandUnit AND
the LandUnit can invade from the transporting unit AND
the LandUnit is on a costal hex Baltic Sea OR stack with the transporting unit
the chance of a successful invasion is > 20 %

B)
It’s in the Baltic Sea the AND
there is a organized LandUnit stack with the transporting unit AND
the LandUnit can invade from the transporting unit
the chance of a successful invasion is > 20 %

THEN

There is threat of an invasion close to Oslo

Threat of invasion close to Narvik
Same as Threat of an invasion close to Oslo, but the sea areas two: Norwegian Sea and/or Artic Sea.

Threat of invasion from North Sea
Same as Threat of an invasion close to Oslo, but the sea area is the North Sea.

Threat of a land advance toward Oslo from Sweden

IF any of the countries at war has (Conquered Sweden or controls Sweden) AND
it has a organized LandUnit AND
it’s in Sweden AND
it’s fast moving (reach the Oslo in two impulses) AND
it’s in supply or can be put in supply or can be reorganized after moving

THEN

There is threat of a land advance toward Oslo from Sweden

it’s fast moving (reach the Narvik in two impulses, without entering Sweden) AND
it’s in supply or can be put in supply or can be reorganized after moving

C)
IF Germany is of the countries at war AND
(Germany has conquered Finland OR Germany controls Finland) AND
Sweden is neutral AND
there is at least 1 German unit in Finland AND
Germany is likely to get another unit into Norway (Ex by invasion/paradrop) AND
Germany has a organized LandUnit AND
it’s in Finland AND
it’s can reach Norwegian territory (in one impulses, by moving trough Swedish territory) AND
it’s in supply or can be put in supply or can be reorganized after moving

THEN

There is threat of land advance toward Narvik from Sweden/Finland

Chance of intervention from controlling power in Narvik

IF Controlling major power has a unit in any of Finland/Sweden AND
it’s in supply or can be put in supply AND
the unit can cooperate with Norway AND
the unit can move and reach within supply range of Narvik or have trace own supply

ELSE IF Controlling major power can railmove a unit into Norway AND

Is there a Marauder setup possible? Norway has a TRS and a SCS, right? so what if BISMARCK is sitting in a reachable port unguarded?

Is there a Marauder setup possible? Norway has a TRS and a SCS, right? so what if BISMARCK is sitting in a reachable port unguarded?

Interesting! But where to land? All SCS in Norway has only 1-2 in range and 3 in movment, giving the Notional min +1 shore bombardment mod , scarifying a TRS is possible to avoid the penalty. Notional units in GE/CW home country has at least + 2 additional in defence. So to successfully land GE/CW home country is hard, in a minor country perhaps, preferably a out of supply hex.

The notional unit has 1 combat factor, modified by:
* +1 if it is a city hex;
* +1 if the hex is in the home country of the major power that controls the hex;
* +1 if it is not stacked with a land unit, but is in the ZOC of a friendly corps or army;
* + the shore bombardment modifier for each invading unit;
* -1 if it cannot trace a basic supply path of any length; and
* -1 if surprised (see 15.).

I cannot see where this enters into your formula, but Narvik is not invadeable from the Norwegian Sea. It is, however, important for the purposes of GER/SWE resource transport in winter.

That’s why the invasion check is close to Narvik, not on Narvik.

Narvik is not invadeable from the Norwegian Sea.

This seems like an issue to me on the new modified Scandinavia map.

Narvik *was* invaded directly from the Norwegian Sea; twice. Both the Germans and the Allies landed troops straight into the port area in 1940 (the British/French/Polish landing at Harstad Isle just 4 miles north of Narvik, the Germans landing directly into the port itself).

Not being able to do this in MWiF is not accurate to history.

Perhaps change the sea area border so that Narvik does have a full sea hexside on the Norwegian Sea(ie Narvik would be a single sea zone port). This would disallow invasions from the Arctic Sea but I don't see that as a problem.

Houston, we have a problem.

RAW says that about invasions :
*********************************
11.14 Invasions
(...)
You may only invade an enemy controlled coastal hex that has at least 1 all-sea hexside (at least part, but not necessarily all, of this coastal hexside must touch upon the sea area where the TRS is located).
*********************************

The problem is that on the paper WiF FE, the Sea Area boundaries can bisect the hexagon side, while in MWiF it never bisects it. When that hexagon side is an all-sea hexside, this means that this all-sea hexside can be used to invade the hex from both sea areas.

In the attached picture this is remarkable on 2 easy examples.

Liverpool has an all-sea hexside that is bisected by the Sea Area Boundary between the Faeroes and the Bay of Biscay, so Liverpool can be invaded from both Sea Areas.
Kristiansand has an all-sea hexside that is bisected by the Sea Area Boundary between the North Sea and the Baltic Sea, so Kristiansand can be invaded from both Sea Areas.

On the MWiF map as you can see, the Sea Area Boundary is following the hexagon side, so it does not bisect the all-sea hexside properly, and make the invasion from one of those Sea Areas impossible by RAW.

Maybe the invasion is possible anyway because the program knows that it is possible and so it allows the player to do it, but it is not reflected on the map.

[Froonp]

In Narvik's case, in WiF FE the hex is clearly invadable from the Norwegian Sea normaly, and not from the Arctic Sea.
On the MWiF map, due to the Sea Area Boundary not bissecting the All-Sea hexside, it seems to be the reverse.

I can modify the Sea Area Boundary as shown on the attached picture, that would allow Narvik to be invaded from the Norwegian Sea, and no more from the Arctic Ocean, but then Narvik won't be a port on the Arctic Sea anymore, like it is on the WiF FE map.

It's not a question of tracing a blue line, it is a question of saying FOR EACH HEX, to which sea area it is adjacent too.
I don't see how I can set the "adjacentcy" so that the blue line is like you propose.

I think I may have a solution, by tracing it this way :
I only need to change the hex NW of Narvik and say it is on both Sea Areas, and the blue line should be here.

PS : What I explained in post #15 still a problem.

It looks like all the ports bisected by blue lines in WiFFE need to be compared with their couterparts in MWIF. Is there a problem making them the same in MWiF - FREX Liverpool and Kristiansand?
