kandi X-RAY | Lagrange Summary
Implementation of different cryptographic algorithms with z3 solver sat. Thanks to that, we transform the AES into different equations. We add the intermediate values (Output of the Sbox, ...) retrieved during side-channel attacks in the system of equations. We resolve the system in order to retrieve the key. Other attack are implemented (Square Attack on round 4).

QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.
You can use the trim function to compare your value safely:
c.state.trim() == val.trim()

I'd like to know how it's possible to obtain the lagrange multipliers from an optimal solution in a Concrete model solved with glpk?
Thanks!

Answered 2021-Apr-08 at 19:59This works for me in gurobi, try it out and tell me if it works with glpk.
You need to prompt getting the Lagrange multipliers / dual variable in pyomo by putting the following line somewhere before solving your model:

QUESTION
I have a pyomo model "m" with 4 variables and several constraints (both equality and inequality) in the form:
Min F(G1,G2,D1,D2) st h=0 g<=0
Then I need to build the lagrangian function, which is something like this:
Briefly, lambda and mu are the duals of the constraints. So I need the objective function + dual1cons1 + dual2cons2 and so on.
I have literally no idea how to do this. The closest I got is with this:
...ANSWER
Answered 2021-Jan-08 at 22:52Pyomo constraints have a body attribute, and uslack and lslack functions that give you a sum expression of the constraint left hand side, the upper slack, and lower slack respectively. The `body attribute is what you want to multiply by lambda and mu. Here is an example with a simple constraint

QUESTION
I implement a Sequential quadratic programming (SQP) optimizer and use ojAlgo for the quadratic programming (QP) subproblem.
My question is: How do I get hold of the "Lagrange multipliers" for the QP solution?
In the attached example code that solve an QP result.getMultipliers() only return an empty Optional.
...ANSWER
Answered 2020-Sep-18 at 09:09I believe that is an Optional because it was (sometimes) too messy to map the Lagrange multipliers from the solver to the constraints of the model.
If you're implementing an SQP solver may I suggest that you don't implement it in terms of ExpressionsBasedModel, but delegate to the convex solvers directly. Build something that implements org.ojalgo.optimisation.Optimisation.Solver and delegate to the various classes in the org.ojalgo.optimisation.convex package. Then you code more directly with the matrices, vectors and multipliers.
To make that solver usable by ExpressionsBasedModel you also implement an org.ojalgo.optimisation.Optimisation.Integration and register that by calling ExpressionsBasedModel.addPreferredSolver(myIntegeration) or ExpressionsBasedModel.addFallbackSolver(myIntegeration).
Implementing a solver and making it usable from the modelling tool are two separate things.

Install Lagrange
You can use Lagrange like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
