P ⊆ RP

P is contained in RP.

Statement

Migrated verbatim from randomized-polynomial-time § Known relationships:

• $\mathbf{P}\subseteq \mathbf{RP}\subseteq \mathbf{BPP}$: RP is a “one-sided” restriction of BPP (which allows two-sided error).

Notes

source: folklore: the claim carried no citation on the page it was migrated from, and none was invented.

class: unstated: no citing page says which notion of reduction is meant. Recording a class the wiki does not state would add a claim.

class: free because a containment between complexity classes is proved by any argument at all; the reduction-class axis does not discriminate here, and unstated would wrongly suggest the information is missing.

Recorded during migration and not fixed — these are claims about the source text, not changes to it:

• The bullet’s gloss justifies only the second containment; this one is left unexplained.
• Uncited and unlabelled folklore.
