When I use the "DistributionInverseCumulative" function for beta distribution, I get the following error message from Visual C++:--Assertion failed!Program: ...Aimms\4.85.5.3-x64-VS2017\Bin\libaimms3.dllFile: c:\gitlab-runner\builds\pvap61xc\0\aimms\a...\beta.cppLine: 173Expression: istat==0--In the MainInitialization I implemented the function as follows:b_p_1 := 6;b_q_1 := 3;b_a_1 := 1;b_b_1 := 5;for n doy(n) := DistributionInverseCumulative(Beta(b_p_1,b_q_1,b_a_1,b_b_1), Uniform(0,1))endfor;For other distributions (e.g. normal distribution) the "DistributionInverseCumulative" works without any problems.I would appreciate any pointers on what I should do so that this function doesn't produce an error message?

I am trying to open a project that was originally written in version 4.37. However I have a Community License so the earliest version I can use is 4.77. I have tried opening this project in both 4.77 and 24.2 and both will crash upon opening the project with no error message.I understand the large difference in versions may be causing an issue but I have no way to test on earlier versions. Is there any way I can identify what exactly is causing this issue and could it be something other than a version issue?

Hi! Does anyone know how to interrupt the calculation process and display the current results?

Hi all, I am aware that AIMMS will use all of the indices specified on the Left Hand Side of an assignment statement to loop over all combinations.When trying out something in a test project I am working on, I wanted to use this logic, but found that this does not work anymore when you are using formatstring on the LHS. Was wondering if this is on purpose or whether this behavior should be possible Example that works:spStringParameter( StringToElement(sTargetSet, iSource, 1) ) := formatstring("Test :: element %e", iSource) ;  Example that does not work:spStringParameter( StringToElement(sTargetSet, formatstring("%e", iSource), 1) :=  formatstring("Test :: element %e", iSource) ;  When running the second one, I get an error indicating that the scope of iSource has not been specified. The above is a minimal example of the problem, not completely the same as what I had. I can work around it by either putting the statement in an explicit for-loop, or create the mapping isource → itarget in

I have one set - Modes, with multiple indexes, mp, m, and mn. These translate to Previous Mode, Current Mode, and Next Mode.In WebUI, I have a table with a parameter that includes two of these indexes, Previous Mode and Current Mode.I’d like to change the name of mp to be Previous Mode and m to be Current Mode. It seems, though, that in fieldnames.properties, I can only change the name of the set (Modes).  Any ideas? 

Dear all, I was very happy to see that an ADLS has been added for every AIMMS Cloud account. We would like to use this, and have found that it works well on the Cloud, however we cannot get it to work locally (from a local AIMMS Developer environment): it looks like we need the Storage Access Key for the ADLS, but I haven’t been able to figure out where to find/access this. Could anyone help us out? Thanks!Meike

Hello!I have a MIQCP problem that I solve in AIMMS. I have tried to solve it both with Octeract and Gurobi. I solve the same problem with different data sets.For one of the data sets, the solving time for Gurobi is 319 seconds and the gap is 0%, while after 1 hour of solving with Octeract the gap is still 420%.For another data set, the solving time for Gurobi is 1834 seconds and the gap is 0%, while after 1 hour of solving with Octeract, the gap is still 9000%.Does this sound reasonable? I am not that familiar with how these two solvers work, but I thought it was a bit strange that the two solvers give very different results.Thank you in advance :)

Anyone happen to know how to hide the scrollbars in a compact scalar widget in a side panel?  This is annoying us: 

Hi everyone!   Is there a way to change if I want to show or not the unit and the number of decimals by parameter?   Example:    My wish: 500     |     0.00%   Thanks.

Dear AIMMS Community,Does anyone have any tips/documentation/experience for moving parameters and data to a different CDM category? (or, perhaps alternatively, create a new parameter in the correct category and then migrating the data). As background: for a customer we are using scenario functionality, with each scenario consisting of 3 CDM categories: master data, dynamic data and planning data. Scenarios can share the same version of this data, e.g. 2 scenarios using the same master data but different dynamic & planning data.Currently the customer doesn't use this option of shared data, because a few parameters within the master data category are actually dynamic. So we want to move these parameters (or perhaps solve it in a different way?) Does anyone have experience with moving data to a different category? We already have many scenarios that we want to keep, so anything we do should leave those intact (in theory that should be possible, because currently none of the scenarios

Hi all, playing around a bit more with the webui and having some more questions.I want to create a dialog page where the user can upload a couple of files and give the name of the scenario into which these input files should be loaded (potentially some other text based input). In the original winUI, I would create something like this (as example what I want to achieve): Now I am trying to achieve this with a dialog page in the webui, but when I want to add a scalar, I get the following: Where I think there is way too much emphasis on this scalar value. I can make use of the experimental feature of compact scalars, but then it looks weird with scroll bars. Also not sure if I can modify the size of the ‘header’ (label showing now spNewScenarioName) and the actual input field: I think the closest I can get this is creating a table with either scalars, or making a set with ‘headers’ to be put in the labels and create an indexed string parameter over this. That way, it starts to look like t

Hi,I have downloaded the newest AIMMS version (24.1) and opened a project using the AIMMS launcher. However, the JSON WebUI file (..\MainProject\WebUI\webui.json) contains this: "version": "4.67.0". Do I have to update the WebUI manually to get the newest AIMMS WebUI version?Thanks in advance.Kind regards,Martijn

Hello, It seems that when you upload a file using the dex::ReadFromFile (dex 23.1.1.2) and using an excel mapping structure like: <AimmsExcelMapping>    <ExcelSheetMapping name="Demand">        <RowMapping>uploading a wrong sheet name does not results in a failure which I would have expected to be. Do I need to add something to the mapping? Or is this not how it supposed to work?Glad to hear any feedback.Marc

Hi All,I’m trying to write a parameter with dex using dex::WriteToFile() procedure. The parameter has an index year that is a subset of the calendar year. (simple calendar with unit year). The excel download won’t fill the year column (see screenshot below). I have the latest .dex library 23.1.1.2).  Could anyone explain what went wrong here?

I want to open dialogpage whenever we open application. I have tried to open dialog page from mainintilisation. its giving error. let me know if we should open dialog page from mainintilisation.

i am displaying info in table. How can we create hyper link under value of cell. if i click hyper link it should redirect to dialogue page with parameter filtered based on value of the cell .

Dear community,I have a question about min and max values for variables. I have a nonlinear problem. What I want to model is that if the variable a(t) has a value larger than 2,000,000, it should be set to 2,000,000. But it is no problem that a(t) is above 2,000,000, it should not be “punished”. I have the same for the minimum value -400,000. When I just set the min and max values in the range of the variable when I define it, it seems that the optimal solution found is one where the variable a(t) does not exceed 2,000,000 or gets below -400,000.Am I right in my understanding of the range of variables? And how do I then correctly impose these constraints?Thank you in advance :)

“outage_status(cd)” is a stochastic Paramater, and “outage_units(cd)” is a set and colects u if  “outage_status(cd)” >0. I wonder whether the data of set “outage_units(cd)” will change with the variable “outage_status(cd)” in different scenarios.   

Hi AIMMS community! I’m currently working on a resource transport model using AIMMS and I've encountered a symmetry challenge for resource balance between zones.In the case when I would like to transport 200MW of power from zone 1 to zone 2, the net outflow of power from zone 2 must be equal to the net inflow of power into zone 1, which can be represented by the equation below:F_in (z,z’) = F_out (z, z’)whereby F_in (z,z’) is represented as the net inflow into zone z (zone 1) from zone z’ (zone 2);while F_out (z,z’) is represented as the net outflow from zone z (zone 2) to zone z’ (zone 1).Does anyone know of an AIMMS function that can seamlessly handle this equation? Any insights or tips are highly appreciated! Thanks so much!

I have set and values are assigned to set after clicking button on UI. I also want to show what are the values are addi=ed to set on UI. can you please guide what is widget suitable for this purpose. I tried with table. below is screenshot for same. But it is displaying 1 addition to set values.

Hi all,We have a relatively simple math program with the potential for duplicate columns. However, knowledge of which variables are duplicates is actually beneficial to the user.While I could go through and examine my parameters/constraints to manually search these, a much faster (computationally speaking) option would just be to have CPLEX report them out to the user, as I wouldn’t need to iterate through lots of parameters. Is there a way I can easily take these warnings from CPLEX and give them to the user? Any help would be appreciated here. Thank you in advance!

I want to check if my identifiers have comments written in it’s attributes. I am writing a procedure to do that. But I don’t know if there is any already existing function to get the comments attribute of a given identifier.

I have created a basic model to read and write excel files. I have created procedure to do that in my model. But when I am creating the download widget in the webui, I cannot access the procedure to download the excel file. And for the matter, I cannot access any of the identifiers as well in any other widget.
