model = highs.Model()

You need to follow the instructions in Getting Started to set up the optimizer correctly.

Solver-specific operations

Parameter

For solver-specific parameters, we provide get_raw_parameter and set_raw_parameter methods to get and set the parameters.

model = highs.Model()

# get the value of the parameter
value = model.get_raw_parameter("time_limit")

# set the value of the parameter
model.set_raw_parameter("time_limit", 10.0)

Information

HiGHS provides information for the model. We provide model.get_raw_information(name: str) method to access the value of information.
