Hi. I am trying a generate a plot of optimality gap vs solution time. For that, I am trying to retrieve incumbent solution, best bound and solution time after every 5 iterations. But, for some reason, I am having issues with callback and I don’t get anything retrieved. Attached herewith are the images giving implementation of callback operation. Could anyone please tell where I am going wrong? Thanks, Sujit
Hey. I am trying to implement a plot in a WinUI that displays simulation progress. In this plot, I am showing a variable value changing with simulation iteration (simulation continues until the iteration value has reached a limit). The variable is not in a math program, hence, I believe I can not obtain its value using callback (using RetrieveCurrentVariableValues procedure). Anyways, the variable gets updated at the end of every iteration. Presently, the plot between the variable value vs iteration does not show when the simulation in in progress (or when procedure is running) and appears after the procedure is over. Is there anyway to update the plot when the procedure in running? Thanks. Here is the structure of the procedure I am running: while (iteration limit is reached) solve Mathematical program1; solve Mathematical program2;Update Plot Variable using variables from math programs 1 and 2; (Plot variable to display in plot)iteration = iteration + 1;endwhile;
Hey. I am working to create a tool (GUI) in AIMMS platform. I have multiple pages in Page Manager for developing the tool. In one of the pages, I want to add an ‘Help’ button, clicking which should open the user manual of the tool (in pdf version - not the AIMMS user manual). Is it possible to implement this?Thanks.
Hi.I am trying to solve a large problem in parallel using asynchronous solver sessions. However, I get this error as soon as I start the simulation ‘The number of simultaneous solves by solver 'CPLEX' exceeds the license limit of 1.' I have CPLEX (Full) solver in AIMMS. Is this because I have a personal node locked AIMMS business license? How do I check the number of solver sessions that I can run simultaneously in AIMMS? Is there a way to activate the Parallel CPLEX option? Thanks.
Hi.I am working to develop a tool that reads some input data from an access database, solves an optimization problem, and then exports results to an output access database. The data import process worked fine when I was accessing the user interface (UI) in page manager. Then, I created an .aimmspack file for deploying the tool for end-user use. Now, when I run the tool from pack file (end-user UI), I get this error during input data reading (image attached). Could someone please help with this error? Could this error be due to me missing to include something during .aimmspack file creation? I have not included the input access database file while creating the pack file. Referring to the image attached, ‘RPS’ is a group in input access database file. Thanks for your help.
Hello, everyone.I have been working to develop a WinUI for an AIMMS project. The UI development is almost over and I am trying to create an executable file (or anything equivalent in AIMMS) for the project so that any user can only access the user interface (without seeing the source code) and run the project. Could anyone please guide me to any resources that explains how to create such executable files? Thanks.
Hi. I have a parameter with index domain (scenario, year). I want to have a plot of parameter (scenario, year) vs year which looks something like in the image attached. In the image, for example, the number of scenarios is two. However, in my project, the number of scenarios changes with user input data. Could anyone please guide me to any resource (example project) in which such type of plots are generated or could give any suggestions how do I proceed to create such plots? Thanks.
Hi all. I am new to AIMMS and need your help with the following query: I would like to place the progress window on a GUI so that the end user can see the solution status and progress. Please let me know how do I do that and also please guide me to any documentations that I can refer for implementing the same. Thanks.
