unexpected output from chimera/pegasus/zephyr_coordinates #258
Description
Description
zephyr_coordinates.linear_to_zephyr and zephyr_coordinates.zephyr_to_linear do not raise ValueError for invalid inputs. Similarly for chimera_coordinates and pegasus_coordinates.
To Reproduce
import dwave_networkx as dnx
Z3 = dnx.zephyr_graph(m=3, t=4)
1000 in Z3.nodes()
returns False. However,
dnx.zephyr_coordinates(m=3, t=4).linear_to_zephyr(1000)
returns (5, 6, 2, 1, 1), which is not a valid Zephyr coordinate.
Expected behavior
I expect invalid input to raise ValueError.
