Optimization subject to constraints

[JScheidegger]

Hi, I’m a newcomer to Knime, and was used to solve problems with Alteryx. While I did find some Optimization nodes set, I was not able to find how to solve a standard linear programming problem. While LP kind of problems share some similarities with mathematical optimization, because both look for maxima or minima of an objective function of a certain number of variables, a linear programming problem differs by doing that under a number of constraints, each of them being also a function of the problem variables. Are there those possibilities on Knime nodes too?

Hi there!

Currently in KNIME there is no dedicated nodes for linear programming. As a workaround you can use R or Python integration within KNIME.

Considering you are coming from a Alteryx feel free to check this topic:

Considering switching to KNIME from Alteryx

Hi there, In a cost cutting effort I am seriously considering closing my Alteryx account and move the the KNIME platform. I want to be a quick study on this, to see if it right for me and my company. I have read comparisons on line between the two, however, what I am looking for is the string of commands in KNIME that are regularly pulled out of Alteryx… Kind of this is what I do in Alteryx to achieve this, and this is how you do it in KNIME. I know that this is cheating on the learning, I …

Are you talking about something like this:

Hi @JScheidegger,

I also come from using Alteryx Designer, hope this can help you and/or you can help update this tool mapping sheet:

Alteryx Designer to Knime

Here is a shared google sheet expanding on the eBook From Alteryx to Knime. Let’s crowd source this and update the Knime tools that would be used to replicate the same functionality. https://docs.google.com/spreadsheets/d/1ecvnm5f-kDhu45CwlQrqmAdct7fyrAHimgUIqP1fxGc/edit?usp=sharing
