Presenting a mathematical model at a technical conference I am supposed to present my work at a technical conference with mostly software/network scientists or engineers and my work is centred around a mathematical model, a MILP, and the related performance evaluations with it. I'm a little confused about whether to present the mathematical model in its full detail (with all the constraints) or just explain using bullets about the constraints in the model and completely skip the mathematical notations.

I find it really hard to decide either of these options and I would love to know your experiences in presenting your work to someone not related to that field. I've observed at some presentations about some of the audience being a little bummed out or not showing much interest in it. But, it would be foolish on my part to presume that whole audience is averse to math. So, I'd like to strike a fine balance between both these themes so as to not to disappoint myself and ensure the audience understands the content. Some of your comments or real-life experiences may come in very handy for my presentation. Oh, and btw, I use beamer for preparing my presentation.
We can be sure you do not have more than 20-25 minutes for your presentation.
As you implied, in such conferences you have to satisfy the novice audience along with the most professional one. So it is highly recommended that you try to present for all of the audience in proper time limits.

In my opinion, SOMETIMES it is necessary to get into some details in order to show the professionals what you did (in reputable conferences mostly). Also you should not make your ordinary audiences bored. So you can show the beginners the big picture such as ideas, examples, etc. (not so much detail) and in some few slides you may want to show some details for your professional audiences, though you do not have too much time for that and you should consider the time limits seriously.

All in all, do not stick in details you give a fair chance no one will care about it. But it does not mean you should skip every detail. Also, try to use your colleagues ideas and feedback in your PRE-PRESENTATION practice about these matters. In my opinion, they are the most reliable resources for us. I myself, really care about my friends and colleagues comments before my presentations or even my paper submissions.
