I am working on the scheduling problem in the class of parallel resource scheduling models. When I have studied some papers regarding that, I see the method that combines an MIP with a CP. The ...

I'm curious about the current prevalence of Markov Decision Processes (MDPs) in medical decision-making. I've seen several research papers on this topic but was unable to find evidence of real-world ...

I am trying to solve Nurse scheduling problem using SCIP. The SCIP solve it in pre-solving stage itself and gives optimal solution. I don't want that to happen., because I want to use the branching ...

I am trying to solve a problem of the form $$\min_{x_1,\dots,x_n} f(x_1,\dots,x_n)$$ subject to a constraint that $\mathrm{length}(\mathrm{TSP}(x_1,\dots,x_n))\leq c$, where $x_1,\dots,x_n$ are all ...

I encountered a minimization problem involving the following function:
$f(\mathbf{x})=\|\mathbf{x}\|_q^p$
Here, $q>1$ and $0<p<1$. Naturally, each entry of $\mathbf{x}$ is greater than $0$.
I ...

I've been dealing with Benders Decomposition and I've been wondering, if I have an unbounded solution of the dual subproblem, is it possible to find out which constraint from the original problem is ...
|
What are common uses of superscripts in mathematical optimization formulations? None of my optimization books start at the level of "proper" variable labeling. When I ask ChatGPT, it ...

Greatest hits from previous weeks:
|
What approaches can I use for a Linear Programming problem with the additional constraint that if a decision variable falls below a certain threshold, then it should just be forced to 0.
I'm ...

Like many who participate in this site, I work on projects in both operations research (OR) and statistics/machine learning (ML). The different states of open source software in these fields are often ...
|
While looking through the job offerings, I noticed that everybody seems to be looking for experienced professionals, senior engineers, or at least three years of industry experience.
Was this just a ...

The Rust programming language is gaining popularity. As the title says, I wonder if state-of-the-art, say MILP, solvers will eventually release APIs for the Rust programming language. Solvers such as ...
|
I see from here and many other sources that Dantzig invented the Simplex method in 1947. After much searching, I found that the earliest publication is this in 1956. Does anyone know where the ...
|
Is there any Python library as published on PyPi, with genetic algorithm (GA) or GA inspired solver that helps with constrained optimization?
I am aware of Matlab's GA solver and also aware that costs ...
|
User ddofborg posted on Stack Overflow a programming question which hides a combinatorial optimisation problem.
The idea is the following: given a list of URLs with their respective domain names, he ...

Can you answer these questions?

I wanted to know whether the Automatic Benders Decomposition from C-plex allows us to solve the sub-problems in parallel over multiple cores. From what I know, one can set the number of threads in ...
|
I would like to package (using pyinstaller) my optimizer program that uses Pyomo and SCIP. I keep getting ...
