Peloton Peloton In a road bicycle race, the peloton (from French, originally meaning 'platoon') is the main group or pack of riders. Riders in a group save energy by riding close (drafting or slipstreaming) near (particularly behind) other riders. The reduction in drag is dramatic; in the middle of a well-developed group drag can be reduced to as little as 5%-10%. Exploitation of this potential energy saving leads to very complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general, as in 'the professional
Bunched logic In perhaps the first use of substructural type theory to control resources, John C. Reynolds showed how to use an affine type theory to control aliasing and other forms of interference in Algol-like programming languages. O'Hearn used bunched type theory to extend Reynolds system by allowing interference and non-interference to be more flexibly mixed. This resolved open problems concerning recursion and jumps in Reynolds's system. Separation logic is an extension of Hoare logic which facilitates reasoning about mutable data structures that use pointers. Following Hoare logic the formulae of separation logic are of the form formula_44, but the preconditions and
