What is cplex AMPL?
AMPL is a mathematical programming and optimization modeling language which can be used to solve linear, integer, and nonlinear programming problems. The AMPL website contains the whole of the AMPL book, a collection of frequently asked questions, and a list of all the cplex options available in AMPL.
How do you use AMPL?
To use AMPL, we need to create a text file with the mathematical program code. To create a text file, you can use any text editor you feel comfortable with. For example, you can use Notepad, which is found on every Windows 95 and Windows NT system.
Which command is used to select the Solver in AMPL?
The solve command causes a description of the optimization problem to be sent to a solver, and the results to be retrieved for examination. This section takes a closer look at the main AMPL features for setting up and solving models.
What is CPLEX solver?
The CPLEX solver from IBM ILOG is a high performance solver for Linear Programming (LP), Mixed Integer Programming (MIP) and Quadratic Programming (QP/QCP/MIQP/MIQCP) problems. A detailed list of all features supported by CPLEX can be found on our Solvers page.
Does CPLEX use branch and bound?
III.4 Using CPLEX for integer programming For problems that contain integer variables, CPLEX uses a branch-and-bound approach.
