Power class. BR: 7F. Nicknames. Super D. The London and North Western Railway (LNWR) Class G2A was a class of 0-8-0 steam locomotives. They were upgraded from LNWR Class G1 principally by the fitting of a higher pressure boiler. Some of the G2As subsequently received lower pressure boilers on overhaul, taking them back into Class G1.
The problem for graphs is NP-complete if the edge lengths are assumed integers. The problem for points on the plane is NP-complete with the discretized Euclidean metric and rectilinear metric. The problem is known to be NP-hard with the (non-discretized) Euclidean metric. [ 3]: ND22, ND23. Vehicle routing problem.

The following is a list of locomotives of the London, Midland and Scottish Railway as of 31 December 1947. This date is significant because nationalisation of the Big Four occurred the next day, 1 January 1948. Thus this is the list of locomotives as inherited by British Railways. At this time there were approximately 8,000 steam locomotives ...
Complete (complexity) In computational complexity theory, a computational problem is complete for a complexity class if it is, in a technical sense, among the "hardest" (or "most expressive") problems in the complexity class. More formally, a problem p is called hard for a complexity class C under a given type of reduction if there exists a ...
v. t. e. Social class in the United States refers to the idea of grouping Americans by some measure of social status, typically by economic status. However, it could also refer to social status and/or location. [ 1] The idea that American society can be divided into social classes is disputed, and there are many competing class systems.
