Adventure Queue

The Hermit humbly requests that this page be rewritten or expanded. Needs further investigation.

The adventure queue is a feature in the game coding that makes high occurances of the same adventure in a short period of time less likely. For example, if you head to the goatlet for the first time and fight a dairy goat, dairy goats will be slightly less frequent for the next several adventures.

Specifically, the way an adventure is chosen is

• Roll for a Superlikely adventure. If not,
• Decide on either combat or non-combat.

• (c) If combat: choose a combat encounter.

• If it's not in the combat queue, that's the encounter.
• If it is in the combat queue,

• 25% of the time: accept the encounter.
• 75% of the time: go to (c) and choose a new combat encounter, subjecting that choice to the combat queue as well.

• (nc) If non-combat: choose a non-combat encounter.

• If it's not in the non-combat queue, that's the encounter.
• If it is in the non-combat queue,

• 25% of the time: accept the encounter.
• 75% of the time: go to (nc) and choose a new non-combat encounter, subjecting that choice to the non-combat queue as well.

Note that once you enter the queue-elimination process, you don't reroll for superlikely or the type of encounter: if a non-combat is first selected you only examine non-combats against the non-combat queue, and similarly for combats. Also be aware that the rejection probability, given above as 75%, is not totally nailed down. It could be more or less than that fraction.

For one type (combat or non-combat) of encounter, with

• E total encounters in a zone, all equally likely,
• j fractional chance of rejecting an adventure in the queue (assumed to be 3/4 or 75%), and
• u unique encounters from this zone in the adventure queue,

The chance of drawing an encounter that is present in the queue is

                 1 - j
 inq(e,j,u)  = ---------
                e - j u

The chance of drawing an encounter not present in the queue is

                   1 
 outq(e,j,u) = ---------
                e - j u
