C++ API Examples¶
This section lists a few examples in C++. These are the same files that can be found in the examples directory of the distribution, and show the basic usage of the C++ API.
Example 1: First steps¶
This example shows how to
read an AMPL model
reassign values to parameters
solve the model
display the objective function value
Example 2: Get and set AMPL options¶
This example shows how to:
get and set AMPL options
Example 3: Get and set data through DataFrames¶
This example shows how to:
Use
ampl::DataFrame
objects to assign values to sets and parametersUse an
ampl::DataFrame
object to fetch and decouple values from a variable
Example 4: Operate with multidimensional data¶
This example shows how to:
Use a
ampl::DataFrame
to assign values to multidimensional parameters
Example 5: Assign all data to a model and solve it¶
This example shows how to:
Assign all the data necessary to generate a model instance programmatically
Example 6: Build an efficient frontier¶
This example shows how to:
build an efficient frontier by repeteatly solve a portfolio problem in AMPL
Example 7: Simple heuristic¶
This example shows how to:
Do a simple heuristics for solving a QMIP problem, using the relaxed solution as a hint
