Re: [Rails-devel] Push request: Enforcement of forced train purchases

[<ste...@we...>]

Erik & Frederick,
I half a 75% finished reply in my draft folder after reviewing the patch.
There is no technical reason to hold the patch (I like both the implementation and
the documentation), however there are two issues
which I believe should be considered: Even if I agree with Fredericks rule interpretation of
"having a route" I am sure that there will be other interpretations (especially if one generalizes
to all possible games and trains) and I would prefer to see a discussion at least on this list,
but it is even more likely that it should end up on the yahoo list.
>From a design point of view I agree with Eriks point of view that it should stay outside of the game engine,
however for different reasons... But here my opinion is not that important as the patch will not
make  into Rails 2.0 anyway.
So please be patient for more details.
Stefan

Betreff: Re: [Rails-devel] Push request: Enforcement of forced train purchases

You are right that parts of the route calculation might be performed
twice. However:

(1) This only occurs if all other necessary conditions for forced
train purchases apply (see lazy route calculation in
OperatingRound.isForcedTrainPurchase).

(2) Even then, this duplication only applies to the initialization of
the network graph, as the second route determination is parameterized
differently with respect to trains (publicly available train types vs.
company owned ones (=zero) for triggering by the UI layer).

For the target design, I fully agree with you. The tricky part would
consist of avoiding duplication during graph construction and route
calculation, given that each OR-step is potentially based on a
different graph (eg., lay tile changes graph for lay token) and works
with different train sets (set revenue vs. forced train purchase).
