Algorithm:

|
|
||
|
|
if (have playable card):
|
||
|
|
if (in endgame) and not (in extraround):
|
||
|
|
stall in the following situations:
|
||
|
|
- we have exactly one useful card, it is a 5, and a copy of each useful card is visible
|
||
|
|
- we have exactly one useful card, it is a 4, the player with the matching 5 has another critical card to play
|
||
|
|
- we have exactly one useful card (todo: maybe use critical here?), the deck has size 1, someone else has 2 crits
|
||
|
|
- we have exactly one playable card, it is a 4, and a further useful card, but the playable is redistributable in the following sense:
|
||
|
|
the other playing only has this one useful card, and the player holding the matching 5 sits after the to-be-redistributed player
|
||
|
|
- sth else that seems messy and is currently not understood, ignored for now
|
||
|
|
TODO: maybe introduce some midgame stalls here, since we know the deck?
|
||
|
|
play a card, matching the first of the following criteria. if several cards match, recurse with this set of cards
|
||
|
|
- if in extraround, play crit
|
||
|
|
- if in second last round and we have 2 crits, play crit
|
||
|
|
- play card with lowest rank
|
||
|
|
- play a critical card
|
||
|
|
- play unique card, i.e. not visible
|
||
|
|
- lowest suit index (for determinancy)

give a hint

if 0 hints:

discard card with lowest badness
|
||
|
|
|
||
|
|
stall in the following situations:
|
||
|
|
- #(cards in deck) == 2 and (card of rank 3 or lower is missing) and we have the connecting card
|
||
|
|
- #clues >= 8 - #(useful cards in hand), there are useful cards in the deck and either:
|
||
|
|
- the next player has no useful cards at all
|
||
|
|
- we have two more crits than the next player and they have trash
|
||
|
|
- we are in endgame and the deck only contains one card
|
||
|
|
- it is possible that no-one discards in the following round and we are not waiting for a card whose rank is smaller than pace // TODO: this feels like a weird condition
|
||
|
|
|
||
|
|
discard if (discard badness) + #hints < 10
|
||
|
|
|

|
|
stall if someone has a better discard
