(We live in algorithms) A book that reviews some algorithms and mathematical equations that are completely suitable for organizing our life affairs and solving our daily dilemmas. From choosing a new smartphone, to buy a house or a car, and even choose your partner, our entire choices are working in the same way: we initially pass through a period of search and comparison between the available options, then we settle on what we think is more appropriate for us. Every time we face a similar situation, and we ask when we can say that we have seen our adequacy of options and we can now make a correct decision?
