Random search (RS) is a family of numerical optimization methods that do not require the gradient of the problem to be optimized and RS can hence be used on functions that are not continuous or differentiable. Such optimization methods are also known as direct-search, derivative-free, or black-box methods.
The name, random search, is attributed to Rastrigin who made an early presentation of RS along with basic mathematical analysis. RS works by iteratively moving to better positions in the search-space which are sampled from a hypersphere surrounding the current position.

A typical Random dude b often appears in places where he's extremely unwanted and even though the people he tries to integrate with make it very clear that they don't want to spend their precious time with this particular random dude b he either doesn´t realise that or he chooses to completely ignore various signals that explicitly express a high level of antipathy for random dude b. sometimes he even goes as far as taking picture with the goup who's unwillingly hanging out with him and he posts them on different social media websites e.g. Instagram. This certain behavior is caused by his need to prove to people that he has 'friends'.

Get the Random mug.Someone who no one really knows, (just seen before and sometimes remembered) but still getting known more frequently over appearing to the same people everyday. (If there are multiple like that there called RANDOMS if there’s one there called a random)
John: “hey Sam, Will, Reed who are you guys again?”
Sam: “I’ve seen you before, you don’t remember me?
Will: “yea you don’t remember me?”
Reed: “yea me to?”
John: “I don’t know you guys, you guys are Randoms , I don’t know I’ll probably start remembering you guys more.”
Sam: “Yea I guess”
Will: “ok”
Reed: “yea I understand”
