How to order a list of records ...

Hello. Here is my question.

> 

 

#GIVEN:

ST := [`162` = Record(mu = 475, sigma = 41), `70` = Record(mu = 480, sigma = 42),
       `168` = Record(mu = 448, sigma = 103)]

[`162` = Record(mu = 475, sigma = 41), `70` = Record(mu = 480, sigma = 42), `168` = Record(mu = 448, sigma = 103)]

 (1)

Games:=[[`162`, `70`], [`70`, `168`], [`168`, `162`]]

[[`162`, `70`], [`70`, `168`], [`168`, `162`]]

 (2)

#I need Maple commands to follow the order of Games to auto create STO please

STO:=[`162` = Record(mu = 475, sigma = 41),`70` = Record(mu = 480, sigma = 42),
       `70` = Record(mu = 480, sigma = 42),`168` = Record(mu = 448, sigma = 103),
     `168` = Record(mu = 448, sigma = 103),`162` = Record(mu = 475, sigma = 41)]

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.
