The color mapping shows the measured value corresponding to each coordinate. In coordination games, players must coordinate their strategies for a good outcome. They are defined as the exterior derivative of the coordinate functions . Conversions between the various coordinate systems are given. Computer programs can often coordinate patches to update a target program. This may involve transformations between or among astronomical and terrestrial coordinate systems. Let be the corresponding nested sequence of "coordinate" subspaces of . Specifically, they are the lines parallel to one of the coordinate axes. Dinitrogen is able to coordinate to metals in five different ways. Unfortunately, the three armies could not coordinate their efforts effectively. Each of these coordinate structures is disallowed. Specifying a location means specifying the zone and the "x", "y" coordinate in that plane. World War I to coordinate their activities. However, large transmitter owners must typically coordinate their operations with the Green Bank Observatory. Alternatively, distributed search processes can coordinate via swarm intelligence algorithms.
