The laptop of a colleague who was sharing the license with me has crashed. Now I want to activate the license in my laptop. I know there is a option for emergency activation but I can not find it somehow. Any suggestions?

Dear all, I have a constraint in AIMMS which is as follows: lambda1(q)*0+lambda2(q)*mu1+lambda3(q)*mu2+lambda4(q)= 1/T(q)*sum[k,sum[l,i(k,l,q)*min(travelTimes(k,l),tau)]]|k in LocationOnRouteQ(q) and l in LocationOnRouteQAfterK(k,q) The problem is in this part: k in LocationOnRouteQ(q) and l in LocationOnRouteQAfterK(k,q) Because I get an error that the scope of index k has not been specified. However, when I put the indices k and l in the index domain I get the error that the scope already has been specified. I want to let the k come out of the set LocationOnRouteQ(q) and l out of subset LocationOnRouteQAfterK(k,q) and I have tried many things, but none worked out. LocationOnRouteQ(q) and LocationOnRouteQAfterK(k,q) are both subsets of the set Locations and I got k and l as indices in the set Location. I hope someone can help me. Kind regards, Aimée

Dear Staff, I would like your tips for an if-then constraint. In particular, I have the following variables: [b]R, binary variable[/b] [b]P, continuous variable[/b] [b]Y, continuous variable[/b] I have the following parameters: [b]A[/b] [b]B[/b] The constraints I would like to write are the following: 1) if R=1 then P = A*Y 2) if R=0 then P = B*Y I would like to know if it is possible to have a linear formulation without using indicator constraints. Thank you,

Hi! We were able to execute the model already but we're having warnings that the result for this column is similar with the other column. Take for example the constraints 22 and 26? How do we code the "summation"? Sorry I'm just a beginner and I have no one to teach me and I only have a month to study everything because the deadline is just for 2 months. Our model in AIMMS can be downloaded here: https://drive.google.com/open?id=1pUgymOpS0-oJLxc_IU6tjt7YEiKkHqmW[img]https://uploads-eu-west-1.insided.com/aimms-en/attachment/4a2b5b92-17a4-4f56-b7a6-8a09a8e94a42.png[/img]

When solving a stochastic program, the results can be accessed using [i].Stochastic.[/i] However, I cannot find this data in the WebUI when trying to make, for example, a table showing the objective value of the stochastic program for each scenario. My question then, is this: how do I show the values of both Decision Variables and the Objective Function for each scenario, resulting from solving a Stochastic Program?

Hi, I have this code that prints the variables to a text file. [code]for IndexVariables do put(IndexVariables); put // ; endfor; [/code] This prints only the first 12 characters of each variable. Why is that? Thanks, WM

Hello everyone, Does AIMMS has a feature that allows me to see the inedex, parameters, variables, obj function and the constrains? I basically want to view the model in a simple way. Thanks!

I've just about got a handle on the css "rules" for the widgets, but the buttons for the new dialog pages don't follow those rules, it seems. I've tried a gazillon permutations of [list] [*].dialog-open [*].dialog-page-container [*].ui-dialog-buttonpane [*].ui-dialog-buttonset [*]button:last-child [*]button [*].ui-button [*].action-cancel [*].ui-widget [*].ui-state-default [*].ui-corner-all [*].ui-button-text-only [/list] How can I change the button color, text color, etc? At this point the only thing that changes anything is [code].theme-mytheme.dialog-open .ui-button-text [/code] and that only changes the background around the text itself, not the button background. Thanks!

Hi there, I am trying to implement some form of heuristic for the TSP where I'm decreasing the size of the model by restricting the declaration of variables X(i,j) to those combination (i,j) for which j belong to the, say, 10 cities nearest to i. Here X(i,j) is an binary variable indicating whether or not edge (i,j) is in the tour. I created a subset of the cities to find the nearest neighbors of city i, but how can I implement it in the model? Do I need to add an extra constraint or? Added you'll find the code of my AIMMS project. Thanks in advance!

Hi! I have a constraint (shown at the photo below) wherein two sets need to be subtracted. I tried introducing another set Kw with a definition of k-Ks but it says subtraction of element valued expressions require the set range to be equal, but the ranges domain set "Subblock" and set "Candidate_Subblocks" differ. Identifier: Subblock Index: k Identifier: Candidate_Subblock Index: Ks Identifier: Subblock_Difference Subset of: Subblock, Candidate_Subblocks Index: Kw Definition: k-Ks above is the current code I have. Do you have any Idea on how I can code my constraint?[img]https://uploads-eu-west-1.insided.com/aimms-en/attachment/aba0c2e6-1091-4ebe-a15c-df90089e980d.png[/img]

Hi! I encountered this problem as I try to recall my data from an excel file. The error says: ExcelRetrieveParameter(FINAL DATA.xlsx, N(E), B16:DQ16, , 0) failed: Actual cardinality (0) of domain #1 is smaller than specified cardinality (120). what should I do?

Hi! I would like to ask what this error means and how I can solve this: ExcelRetrieveParameter(FINAL DATA.xlsx, nC(v,T,w), C3:ALN22, , 0) failed: The dimension of parameter "nC(v,T,w)" is 3. It must be equal to or smaller than 2. I hope anyone can help me with this. Thank you!

I'm a beginner and I know nothing about programming so Im just basing everything from the user manual. I have a parameter with a "nC' as identifier and index domain: v,t,w. The problem is when I try to save it there's an error saying "The symbol ";" is not expected." How do I fix this?

I need to mask my indexes names in WebUI tables the same way is possible to do in WinUI pivot tables using an string parameter. How I can do it? [b]Example:[/b] Set Frubas := { '1', '2', '3', '4'} Ps_DescriptionFrubas('1') := "First" Ps_DescriptionFrubas('2') := "Second" ... In my WebUI table it appears as 1, 2, ... and it should appear "First", "Second" ...

Hi, the "objective function" of my program is read as a variable in AIMMS. All the parameters in the objective function already have a data read from excel. My problem is, AIMMS keeps on saying "the scope of index i has not been specified" when I try to specify the index, the program won't run because it will say that the objective function should be a free scalar variable. What should I do?[img]https://uploads-eu-west-1.insided.com/aimms-en/attachment/804dac29-31b9-4266-89c9-ed78ee2c7c4c.png[/img]

I'd like to launch WebUI automatically upon opening a project. I can't seem to locate the [b][i]webui::pr_OpenWebUI[/i][/b] procedure. Is there one? Thanks! ~Bon

Hi, How can I empty all sets except 1? I only want to empty self declared sets. I tried it with a for loop. However I have some trouble comparing the name of the set with a string. Kind regards, Wiet

The help feature for using a function is very nice: [img]https://uploads-eu-west-1.insided.com/aimms-en/attachment/ae9e8873-838e-44cb-b793-7315307b7c7a.png[/img] The auto-populate for inserting an element is also swell.

Is there a keyboard shortcut for that? Thanks! ~Bon

Hello, I have created two histograms using "Histogramcreate" where the "HistogramSetDomain" are the same but the frequencies observed (using "HistogramGetFrequencies") are different. I have also drew the plots of the histograms separately. I am wondering if it is possible to show the two frequency histograms on the same plot? I appreciate any help in advance

Hello 1- I will try different constraints for my model. For example, I want to disable all constraints and show the results. I tried to created parameters as a below; parameter: IsDisable , range=integer Constraint: MyConstraint , index: (i,j) | not IsDisable But in index section in MyConstraint: " t | t>=2 " I could not add the " | not IsDisable " 2- Also How can I write the solution to excel? Could you please help me? Best Regards.

Hi, I'm making a model of flexible flow shop for academic project and I have a problem with declaring one set(or sets in fact). The set I'm talking about is a set of parallel machins which are bounded to specific stages. It looks more or less like this: [list] [*]t - stage index, t = 1, 2, 3, . . . , k [*]i - machine index, i = 1, 2, 3, . . . , mt (t is upper index) [/list]Do I have to specify every set of machines seperatly for each stage or is there some convinient way of doing it?

Hi all, For our program, we have a 3*36 parameter input that we want to vary using a normal distribution for 1000 times in order to save the objective values to, eventually, create confidence intervals. We have the 1000 variation matrices, but we do not know manage to load these into AIMMS and let the program save the 1000 objective values. On the other hand, it is impossible to copy-paste these manually. Could you perhaps give us some advise on how to implement such a for-loop in AIMMS? Kind regards, Marten

Hi, For one of my projects, I would like to use the functionality multi-objective optimization with tolerance via the procedure GMP::Column::SetAsMultiObjective. Unfortunately, the results are not as I expected. Therefore I made a very small example to test this procedure. In the example, we have one variable (x1) which is nonnegative, one constraint (c1: x1 smaller or equal than 10) and two objectives: (obj1: x1 and obj: -x1). Moreover, the direction of the model (ex1) is maximize. To solve the example, I used the following code: myGMP := GMP::Instance::Generate( ex1 ); GMP::Column::SetAsMultiObjective( myGMP, obj1, 2, 1, 2, 0); GMP::Column::SetAsMultiObjective( myGMP, obj2, 1, 1, 0, 0); GMP::Instance::Solve( myGMP ); Based on the first objective (with the highest priority), I would expect the solution to be x1 = 10. Then, since we also have a second object and we allow the obj1 to have an absolute tolerance equal to 2, I would expect that the final solution would b

I often have thoughts/suggestions/questions on the documentation that have only to do with the understanding of the language (not AIMMS or anything mathematical). Do we have a sub-forum that users can ask or discuss things about that? In particular, right now I'm once again running into the situation where the documentation shows the text representation, but yet AIMMS doesn't allow the ability to directly code in text. So I'm wondering if there's a place in the documentation that shows how to convert text representation into what to put in the AIMMS GUI. Thanks! ~Bon
