tex2solver

@evrenguney Thanks, Evren! We're thrilled to see tex2solver working for you!

Wow @tex2solver is really working. I wrote a model on paper and in 3 steps it is solved by cplex LP solver. Great job! The OCR is also great, it understood and converted my handwriting perfectly.

@evrenguney Hi, Evren! Thanks for helping to test things out. We'll DM you to get a little more info so we can get this fixed.

@tex2solver hi there. I tried to sign-up but whatever email I tried it doesnt work. Can you please check your sign-up process? :)

Achievement unlocked: Solving a linear program on a phone. No software to install. Take a picture of an LP, get a solution in return. The demo in this video uses the CPLEX solver on @NeosOpt servers.

Today's a big day! We are very proud to introduce AIMMS Community Edition, a free entry point for anyone interested in building mathematical optimization models and applications using our feature-rich IDE ow.ly/pqqo50E27jX #AIMMS #ORMS #datascience

Should also mention that this new feature was made possible with the generous support of our friends at @AIMMS. Join the discussion at community.aimms.com/developers-mat…. Your feedback helps us improve tex2solver.

tex2solver now converts integer and linear programs to @AIMMS syntax! Try it out at tex2solver.com. youtu.be/ED6HcKb4Daw

Did you miss our session? No problem...the tex2solver talk is available on YouTube: youtu.be/WNGrgC1aFfs

Our session at the #informs2020 Annual Meeting is happening now! Lots of interesting and varied talks on optimization. We look forward to chatting with you at 10am EST. cattendee.abstractsonline.com/meeting/9022/S…

@GeoffreyDeSmet @GeoOptimization Very nice API, Geoffrey, which seems well-suited to address the different challenge/audience you've described. tex2solver aims to save time for those who already have an IP/LP model, by automating the translation to solver code. For example: youtu.be/p6Eg6wHfEAs

@tex2solver @GeoOptimization Impressive text recognition, but to solve the problem that business analysts can't program mathematical constraints, I don't think the answer is to copy paste math equations that they don't understand. I believe in a UI layer on our ConstraintStream api: optaplanner.org/blog/2020/04/0…

New video: Solving a linear program...from a screenshot...without writing any code. tex2solver converts MILP models to solver code. Test it out at tex2solver.com #optimization #orms

@ORatWork Thank you, John! We wanted to help people validate their models as easily as possible. Hopefully this will also encourage students to further explore the art of modeling. Would love to get your feedback if you get time to test it out.

Using tex2solver on your smartphone, you can take a picture of your linear or integer programming model and automatically generate the solver code. Here's an example with a handwritten LP model. tex2solver.com

3) Here are some examples of decision variable definitions that tex2solver recognizes:

2) Constraints should begin in the second line of the model, which should start with any of these LaTeX text tags (the text itself is case insensitive):

#orms community, We're trying to compile some generally-accepted best practices for formatting IP/LP models...we need your input! What are your DOs and DON'Ts when it comes to writing an MILP? Any formatting issues that you frequently point out during peer reviews?

Happy to report that our #informs2020 presentation has been uploaded. Whew! The entire presentation is available at youtu.be/WNGrgC1aFfs

@thyunes @mluebbecke Hi, Tallys. You're correct. For LaTeX -> code, we need the mapping to indicate which elements of subscripts and/or superscripts are actually indices (vs. parts of the variable name itself). Some more details are documented here: #latex_math_model" target="_blank" rel="nofollow noopener">tex2solver.com/help.html#late…

@mluebbecke From text to code: I'm guessing the issue arises when summations are written out in expanded form instead of using sigma. You see x1 + x2 + ... and there could be an i and a j index set and you're not sure if this is xi or xj?

@spineda_uma Thank you!

So cool!

@ROberdieck @derduff Thanks, Richard. Please let us know how it works for you. We're looking for feedback so we can improve the system.

@derduff @tex2solver It seems so, at least they have a demo for it on their website. Looking forward to playing with it.

@derduff Thank you! Yes, summations, set operators, conditionals, and others are currently supported. Our work-in-process documentation provides some details: #latex_math_model" target="_blank" rel="nofollow noopener">tex2solver.com/help.html#late… Please do let us know if we've missed something.
