Assembly:  Microsoft.Solver.Foundation (in Microsoft.Solver.Foundation.dll)

public static Term Sos1(
	Term referenceRow
)

Parameters

referenceRow
Type: Microsoft.SolverFoundation.Services.Term
A reference row.

Return Value

Type: Microsoft.SolverFoundation.Services.Term
A constraint for a special ordered type 1 set.

The input must be of the form c1 * d1 + c2 * d2 + ... where cN are constants and dN are decisions. None of the constants can be zero, and the same constant cannot appear more than once. The SOS1 constraint enforces the property that at most one of the given decisions can be nonzero. The constants should be associated with the problem in some natural way. The ordering of the constants is used by the solver to find a solution more quickly.
