Nobody here wants to reveal their hideous human faces to fellow Dominion nerds.

You friended me on Facebook ...  :)

The typical format is 3-4 player games for RGG sanctioned tournaments.

A number of past tournaments have run with a $5 entry fee and promos and/or store credit prizes.

Help! / Re: Base game kingdom with no trashing

I was able to hit 39/57 coins on turn 17/18 in a test game playing Poacher/Market/Throne Room/Laboratory/Vassal (adding Merchant only when the other piles ran out).

With optimization, the engine might be a turn faster.

Laboratory is the most important early (to draw deck).

Once over half of the deck is actions, Throne/Vassal builds up a bit more quickly than Poacher.

The engine will sometimes lose to Council Room + BM hitting 40-43 points, but most of the time, Council Room will struggle to pick up the last few points.

Nice article, keep it up!

The +card token on Magpie is really good.

Peasant/Magpie opening into Mission with Bonfire on the extra turns looks quite good.

Just had a crazy fast Stonemason/Quarry/Villa game (3 turns).

Turn 3, draw Quarry + 4 Copper.
Stonemason -> 2 Villas (5 times).
Stonemason -> 2 Trade Route (4-5 times).
Win off museum points.

Jimbo had Quarry in hand, but never got to play his third turn!

Dominion General Discussion / Re: Ambassador and When to Buy Curses
« on: March 21, 2018, 12:14:20 am »
Ambassador presents the threat of giving out ten curses. If my opponent falls behind or greens to early, buying a curse is an effective way to punish the stumble.

In close games, buying a curse is usually hurts you more than your opponent.

It's one of those things where the threat of incoming curses makes you play differently. And if your deck is strong enough, your opponent won't buy a curse. So even though the curse isn't bought most games, the threat of a curse being bought changes the dynamics of the game.

Dominion Articles / Re: What's stopping AI from mastering Dominion?
« on: March 02, 2018, 03:18:55 pm »
Dominion is a hard game. In the original AlphaGo paper, games are described by two parameters: the number of decisions, d, and the typical number of legal moves, d. For chess, d~80 and b~35, whereas for dominion, d~200 and b~10.

The decisions in dominion games are also quite different. In chess, each move is played on the same board, whereas in dominion, deciding which action to play is much different from deciding which card to buy or which card to trash. The difficulty of the problem is further increased by the presence of randomness and hidden information.

Fortunately, the state space can quickly be made tractable with a few simplifying assumptions. Instead of enumerating all possible states of a deck, the mean-field approximation can be used to describe the average card in a deck. For example, the starting deck produces an average of 0.7 coins/card and 3.5 coins/turn. With this model a payload function consisting of coins, buys, attacks, gains, attacks, cards trashed, and VP gained can be maximized, which allows for an analytical solution for most decisions.

Of course, some decisions are hard. These questions are best approached through the lens of machine learning. Difficult single decisions, such as how to use a remodel, can be approached with Monte Carlo Tree Search (MCTS). Each possible option is enumerated, play continues, and the choice that led to the best outcome, on average, is selected. Parameters in the global model, such as the payload function, can be optimized through a series of bot tournaments on a particular board.

The greatest advantage that AI has in dominion is its speed of play. Being able to play multiple games a second means that an AI can check for patterns and interactions far faster than a human can. With sufficient computational power, "perfect" dominion play is possible, although in practice finite resources are always available. The trick then is to determine which simplifying assumptions can be made to construct a bot that plays "very good" dominion.

Dominion Articles / Another Puzzle
« on: February 25, 2018, 05:04:18 pm »
Here's another puzzle:
Win a solo game on turn 8 on the board shown below.

How to load the game (1-player):
1. New table
2. Set min and max players to 1
3. Create table
4. Advanced options->load game 12023791, decision 0
5. Play game

It's possible to peek at the solution I found by loading at the last decision point.


Beating Lord Rattington 1,000 times unlocks the perfect shuffle luck achievement.  ;)

Super hard mode: Open Counting House

For the normal modes, I like opening Chapel/Village into Masq. Chapel/Poacher, Masq/Masq, and Masq/Poacher are also playable.

The turn counter can be deceptive, particularly for different random seeds. With perfect shuffle luck, a megaturn is theoretically possible on turn 8, with turn 10-11 being more realistic. The average time to Province-out in my test games was between 12 and 13 turns. Imperfect shuffle luck adds a few turns to the average case, as one might expect.

For this type of challenge, it's really helpful to have a standardized random seed so that results can be compared with consistent shuffle luck.

Winning with style > winning

Of course, it would be the right move if, even after trashing the Provience(s), you still have more than 50% of the possible available VP.

At the point where you have already achieved victory, nothing is "wrong" or "right" from a strategic perspective...short of throwing the game.

After the win, the rest is meaningless fluff.
