Xpress base functions
|
Declares an output callback function in the global environment, called every time a line of message text is output by any object in the library.
|
|
|
Creates an equality constraint from two expressions.
|
|
|
Returns the evaluation of one or more expressions for a given assignment of values to optimization variables.
|
|
|
Returns the full path to the directory of examples of the Xpress Python interface module.
|
|
|
Returns True if the provided feature is available in the current license used by the optimizer, False otherwise.
|
|
|
Releases the Xpress environment, thus freeing up one license.
|
|
|
Creates a greater than or equal to constraint from two expressions.
|
|
|
Returns the banner and copyright message.
|
|
|
Returns whether checking and validation of all Optimizer function calls is enabled for the current process.
|
|
|
Queries whether the current application is allowed to use the Insight Compute interface.
|
|
|
Returns True if comparing two expressions using the ==, <= or >= operators creates a new constraint.
|
|
|
Returns the number of days left until an evaluation license expires.
|
|
|
Returns the last error encountered during a call to the Xpress global environment.
|
|
|
Returns the error message string describing the last licensing error, if any occurred.
|
|
|
Returns True if Optimizer messages will be written to the Python output stream, False otherwise.
|
|
|
Returns the full Optimizer version number as a string of the form 15.10.03, where 15 is the major release, 10 is the minor release, and 03 is the build number.
|
|
|
Returns the Optimizer version numbers split into major, minor, and build number.
|
|
|
Initializes the Xpress environment prior to creating or reading a problem.
|
|
|
Compares two Xpress objects for equality.
|
|
|
Creates a less than or equal to constraint from two expressions.
|
|
|
Removes a message callback function previously added by xpress.addcbmsghandler.
|
|
|
Sets whether to force the same execution path on various CPU architecture extensions, in particular (pre-)AVX and AVX2.
|
|
|
Disable/enable some of the checking and validation of function calls and function call parameters for calls to the Xpress Optimizer API.
|
|
|
Set whether the current application is allowed to use the Insight Compute interface.
|
|
|
Enables or disables the behaviour where comparing two expressions using the ==, <= or >= operators creates a new constraint.
|
|
|
Sets one of the module's controls to its default value.
|
|
|
