## Searching for the Efficient Frontier...

HI

Hot on the heels of my previous question https://www.mapleprimes.com/questions/227935-Multiply-Contents-Of-Vector-To-Get-Expected-Value#answer262336

I have attempted to maximize growth while keeping variance below a fixed level (with not much success), but

can any of you maximize the growth of a 3 stock portfolio while minimizing the variance.

## How to do I make it work properly?...

Hi everybody!

Quick question for you guys. I have access to Maple 2019 on my main computer and Maple 2018 on a remote Desktop (but I don't want to use because it's super slow and bad (normal rdp stuff)). The problem I have is for the same document, same line, same instruction, Maple 2019 on my computer is failling to do it correctly (unable to do the matrix correctly) and in the Remote Maple 2018 it's doing it just fine. I really don't understand. If someone can give me a little help it would be highly apreciated!
