I am not a match geek, but I was learning about Bayesian theorem and how it can help me make better decisions. It is simple yet complex, can someone please guide me, so I can simply put the number in excel and it calculates for me? I read that value of some variable can not be more than 1.0; in excel, I can format a cell to never accept value more than 1.0. I sort of want to create a general model to calculate different aspects of my life. Currently I want to now the probability of my gf mood. Data I know is She get's happy when I compliment her and she herself say that I should appreciate her, most of the fight occurred because I forget to complement her efforts before complaining. she recommends that I should praise before complaining. So not praising mean more probability she will get angry. Now can someone for love of god, help me create a Bayesian formula for this, so that I know that after how long it's time to complimented her for this long and I should compliment her. I know I should just follow the emotion and compliment her when I feel like, but you don't get the problem, it is timeconsuming and I want to optimize so that I spend less time doing so.

You're asking too much of mathematics.

The closer you can get the ratio of complaints over compliments to zero the higher the girl's smile index. It is a well known law of erotology. And while your smile index may be raised by complementing your girl friend with one or two others, complementing has been shown to have a nonzero probability of shortening your life expectancy. By the way, I do not believe the Reverend Bayes experimented with girl friends: it might have scandalized the parish. Last edited by JeffM1; August 3rd, 2017 at 05:50 AM.

Honestly this is hilarious. But I think it is more of an optimisation problem, as you have realised. In any case, you need to start collecting data. Record how long a compliment will last, which ones are more effective and under what conditions etc. formulate a list of constraints. And think more abstractly. You are a company that produces products (compliments), your girlfriend is a consumer of your product (your free, product, might I add). Supply, demand, time and cost management. It's all there.

There's a reason nobody (in their right mind) uses mathematical models to make lovelife decisions.... What you need to do is get off this website and surprise her with an amazing surprise candlelit dinner, spontaneous holiday, pampering session or something else romantic and adventurous. Pull out all the stops! Make it personal and about both of you, not just her. If she still complains after that, find someone else who won't. Nobody has to live the life of a slave and do the bidding of her every whim (not until you're married anyway! )
