uvarty

UVARTY − CUTEr tool to determine the type of each variable.

CALL UVARTY( N, IVARTY )

The UVARTY subroutine determines the type (continuous, 0-1, integer) of each variable involved in the problem decoded into OUTSDIF.d in the case where the only possible constraints are bound constraints.

The arguments of UVARTY are as follows

N [in] - integer

the number of variables for the problem,

IVARTY [out] - integer

an integer array whose i-th component indicates the type of variable i. Possible values are 0 (a variable whose value may be any real number), 1 (an integer variable that can only take the values zero or one) and 2 (a variable that can only take integer values).
