So few mathematicians know about linear optimization because it is a specialized area within the broader field of mathematics. Linear optimization involves solving complex mathematical problems using linear programming techniques, which may not be widely covered in standard mathematics curricula. Additionally, linear optimization is often taught at the graduate level, so many mathematicians may not have been exposed to it during their undergraduate studies. Furthermore, the application of linear optimization is more prevalent in specific fields such as operations research, economics, and engineering, which may limit its exposure to mathematicians in other areas of study. **
