In my opinion only? I agree that AD is essential. There's Pyomo. What about autograd? Number of nonzeros in equality constraint Jacobian Mizux added the Help Needed label Mar 9, We have no plan to support non linear math optimization. This part covers three main topics through nine chapters. The first topic focuses on the design of such MOO problems, their complexities including nonlinearities and uncertainties, and optimality theory. The second topic introduces the founding solving methods including the extended simplex method to linear MOO problems and weighting objective methods.
Mixed Integer Nonlinear Programming (MINLP)
The third topic deals with particular structures of MOO problems, such as mixed-integer programming, hierarchical programming, fuzzy logic programming, and bimatrix games. It is an essential handbook for students and teachers involved in advanced optimization courses in engineering, information science, and mathematics degree programs. Real-world problems may require large-scale systems with particular features. Thus, water resource systems WRS can be described by large-size multi-objective optimization systems. In our toy example, from Getting started with AMPL let us modify the declaration of variable x as follows:.
The Knitro log now mentions 3 integer variables, and displays additional statistics related to the MIP solve. However, if for instance you change the first constraint to:.
The function signature is very similar to knitromatlab , but three additional argument arrays are used. The most elaborate form is:.
Mixed Integer Nonlinear Programming Solvers
The array xType sets the variable types and must be the same length as x0 if it is used. Continuous, integer, and binary variables are set with 0, 1, and 2, respectively. Passing an empty array, , is equivalent to an array of all zeros. The scalar objFnType sets the objective function type. Uncertain, convex, and nonconvex are set with 0, 1, and 2, respectively.
Passing an empty array, , is equivalent to passing zero. The array cineqFnType sets the inequality constraint function types and its length must be the same as the number of inequality constraints. Linear constraints are known to be convex, and nonlinear equality constraints are known to be nonconvex, so they are not included in the array.
Uncertain, convex, and nonconvex inequality constraints are set with 0, 1, and 2, respectively. Passing an empty array, , is equivalent to passing an array of all zeros. Again, this example is quite unusual in the sense that the continuous solution is already integer, which of course is not the case in general.
A MIP problem is defined and solved via the object-oriented interface by adding additional problem information in the problem class. The ProblemExample class has to be extended with new definitions. Without specifying a variable index, the function sets variable types for all variables to integer. Many user options are provided for the MIP features to tune performance, including options for branching, node selection, rounding and heuristics for finding integer feasible points.
It is recommended to experiment with several of these options as they often can make a significant difference in performance.
