[Missing Yogurt dataset for Using Mixed Integer Linear Programming To Solve Optimization Problems training]

Thank you.

[Interrupted computation during processing]

What do you mean by "debug exports"?  Just exporting the data to an Excel file and then link the next task to this Excel file?

[Missing Yogurt dataset for Using Mixed Integer Linear Programming To Solve Optimization Problems training]

I am not taking this course in Rulex Academy.  I accessed the documentation via the Help Manual Search icon in RuleX.  I did a search on "Mixed Integer Linear Programming" to bring up the documentation.  In the documentation it says to click on the link to get the Yogurt dataset.  Below is an excerpt from the documentation.  When I click on the link "yogurt", I do not see the yogurt dataset.

In the Using Mixed Integer Linear Programming To Solve Optimization Problems training, it says it uses the Yogurt dataset but when I click on the link I do not see it.

[Empty attributes in the output table]

How do you create a table with the list of weeks using the enum() function.

[What exactly is None]

In the documentation, it has

None is None, produces the result True

None not is None, produces the result True  <= is this wrong ... should it be None not is None, produces the result False instead of True.

What exactly is None?  Is it a space " " or "" or Null?

When I want to filter, should I use "==" or "Is" or does it make a difference?

[Repeat a set of steps]

I need to repeat a set of steps multiple times.  Right now, I just have all the steps copied four times..  Is there a way to loop through a set of steps a set number of times.

[Why does my History disappear when I added a new attribute]

If it detects an error in the History, then all the History is deleted when I hit SAVE.  I sometimes gets the message "Warning in Save Operation.  Error in operation session Task.Save.  Saving history you will lose some operations.  Do you want to continue?  It seems once I get this message I cannot get rid of it and I have to select Save and then all or most of the histroy disappears.

[What is the reason to do a "Reset Query"]

Also, where in the Technical Documentation does it explain the user of Reset Query?  Is the only way to know you have a Reset Query is by looking at the History?

[What is the reason to do a "Reset Query"]

Couldn't you just use a formula var_2 =  ifelse(var1 = "A or var1 = "D",2," ")   I do not see the benefit of using a preFilter and then deleting it.  It seems like doing this behind the scenes would make understanding what was going on with your data more difficult to understand because you would have to look through the History to see this code.

[Why does my History disappear when I added a new attribute]

Why does my History disappear?  I created a new attribute and I select Save and the previous History just is gone and I only have the Add Attribute in my History.  What am I doing wrong?  Very frustrating.

[Variable occurrence]

In the Export to Excel File options, is there a way to dynamically create the File basename and Sheet name using values in a DataManager.  Then, filter the DataManager to export to the Excel file the rows that contain the basename and sheet name values.
