In science:

For handling these variables, one can introduce an additional joker state which we denote by a “⋆”.
Constraint Satisfaction by Survey Propagation
Correspondingly, the new message is sent if this vertex is not fixed to a single color, i.e. if it is in the joker state.
Constraint Satisfaction by Survey Propagation
Internally, this matching engine produces a list of sub-sequences which carry annotations which part of the pattern they matched, or if they lie between patterns, plus information about identifications of jokers within these patterns.
A novel approach to symbolic algebra
Furthermore, there are other special classes of jokers that e.g. match a sublist of arbitrary length of a given list (an inherently nondeterministic specification).

Exhausting strategies, joker games and full completeness for IMLL with unit.
Simple free star-autonomous categories and full coherence
Exhausting strategies, joker games and full completeness for IMLL with unit.
Simple multiplicative proof nets with units
For this last case we have introduced the unifying joker state ∗.
Message passing for vertex covers
Note that also this information is sufficient to be exploited algorithmically: If a vertex is assigned the joker state, it can be chosen liberally to be covered or to be uncovered during graph decimation.
Message passing for vertex covers
In this case, we therefore find ˜πi = ∗, i.e. vertex i is found to be in the joker state.
Message passing for vertex covers
We see that in this rule no difference between always covered and joker vertices j ∈ N (i) exists, which explains the use of the minimum warning in definition (6).
Message passing for vertex covers
The color coding of the vertices corresponds to the values of ˜πi and the ˜πj |i : Value zero is represented by a white dot, value one by a black dot, and the joker value ∗ by a gray dot.
Message passing for vertex covers
The prefactor 1/2 in front of the number of joker vertices is not a direct result of WP.
Message passing for vertex covers
For the derivation of the second expression we have used that the single non-zero warning among the messages reaching a joker vertex can be chosen liberally in between all d incoming edges.
Message passing for vertex covers
Inside such a cluster of minimum VCs, a vertex i may either be always covered (state 1), never covered (state 0) or sometimes covered and sometimes not (joker state ∗).
Message passing for vertex covers
For small random graphs as used in Ref. , it is very likely that all the minimal VC solutions can be grouped into a single cluster (but with long-range frustrations among those vertices described by the joker state ∗ ).
