In science:

They studied whether an agent equipped with pebbles can infer the size of the polygon in this setting.
Simple Agents Learn to Find Their Way: An Introduction on Mapping Polygons
They showed that with a single pebble this is not possible, conjectured that two pebbles are also still insufficient, and showed that three pebbles allow computing the size of the polygon.
Simple Agents Learn to Find Their Way: An Introduction on Mapping Polygons
Gfeller et al. showed that an agent with a pebble cannot approximate the number of points within a factor of 2 − ε, for any ε > 0.

For instance, the agent may have a pebble (cf.

Pebble games with algebraic rules
The general framework we introduce includes as special cases the pebble games for finite-variable logics with and without counting.
Pebble games with algebraic rules
An important class of such tools are the so-called pebble games, which are variations and extensions of the Ehrenfeucht-Fra¨ıss´e game for first-order logic.
Pebble games with algebraic rules
In particular, the k-pebble game characterises the relation ≡L k of equivalence in first-order logic with k variables.
Pebble games with algebraic rules
Duplicator must respond by placing the matching pebble in the opposite structure.
Pebble games with algebraic rules

Pebble games with algebraic rules
Assume at the end of the round that r pebbles have been placed and let {(ai , bi ) | 1 ≤ i ≤ r} ⊆ U(A) × U(B) denote the r pairs of pebbled elements, such that for each i the label of the pebble on element ai is the same as the label of the pebble on element bi .
Pebble games with algebraic rules
We say that Duplicator has a winning strategy in the k -pebble game if she can play the game forever, maintaining a partial isomorphism at the end of each round.
