Utility Routines

Functions
int	COI_Solve (coiHandle_t cntvect)
	method for starting the solving process of CONOPT.
void	COIGET_Version (int *major, int *minor, int *patch)
	returns the version number. It can be used to ensure that the modeler is linked to the correct version of the CONOPT DLL.
int	COIGET_MaxThreads (coiHandle_t cntvect)
	returns the maximum number of threads that can be used by CONOPT.
double	COIGET_MaxHeapUsed (coiHandle_t cntvect)
	After a model has been solved this method will return the amount of heap memory used.
int	COIGET_RangeErrors (coiHandle_t cntvect)
	returns the range errors that were encountered.

Detailed Description

This section describes utility routines in the CONOPT DLL.

These methods are called to start the solver and retrieve information about the solver.

Function Documentation

COI_Solve()

int COI_Solve

(

coiHandle_t

cntvect

)

method for starting the solving process of CONOPT.

Parameters

cntvect

the control vector

COIGET_Version()

void COIGET_Version	(	int *	major,
		int *	minor,
		int *	patch )

returns the version number. It can be used to ensure that the modeler is linked to the correct version of the CONOPT DLL.

Parameters

major	major version number
minor	minor version number
patch	patch version number

COIGET_MaxThreads()

int COIGET_MaxThreads

(

coiHandle_t

cntvect

)

returns the maximum number of threads that can be used by CONOPT.

If you are using multiple threads it may be necessary to know in advance how many threads CONOPT can use. If called inside a parallel loop, this method will return one—indicating that CONOPT cannot use multiple threads when CONOPT itself is called in parallel. Therefore, this method should be called in some sequential initialization code and not inside a function evaluation routine, that could be called in parallel.

Parameters

cntvect

the control vector

COIGET_MaxHeapUsed()

double COIGET_MaxHeapUsed

(

coiHandle_t

cntvect

)

After a model has been solved this method will return the amount of heap memory used.

Parameters

cntvect

the control vector

COIGET_RangeErrors()

int COIGET_RangeErrors

(

coiHandle_t

cntvect

)

returns the range errors that were encountered.

Parameters

cntvect

the control vector
