comment Why doesn't FullSimplify work properly on this?
Note that $1+R+R^2+R^3+R^4+R^5+R^6$ requires 5 multiplications to be implemented, while $1+(R+R^4)(1+R+R^2)$ requires only 3! That is why a more factorized form is desirable.

comment How can you compute Itō Integrals with Mathematica?
Well done. Can you implement the Euler-Maruyama or SRK method for finding the weak solution of Black-Scholes SDE in Mathematica?

comment Is there any fast way to solve a quadratic matrix equation in Mathematica approximately?
The applied norm is optional (Frobenius or Infinity). Just finding some approximate valaues for the scalars in any fast way is needed.

comment How to use adaptive precision in matrix computations?
Can you write it down, please? Does it reduce the whole computational time?

comment How to use adaptive precision in matrix computations?
Thanks for your comment. I do agree. However, I think some built-in functions of MMA already do such an action. An example is the function FindRoot[], which applies the precision of the input data (function and the initial guess) and then improve it per cycle. Also, applying the adaptive precision in matrix calculations (such as the above concrete question/idea) is very good in high precision computing environment. It should reduce the computational time dramatically for large scale problems.

Please write a code solution based on your tip. I am not familiar with your suggestion.

comment How to use Compile for accelerating matrix multiplications?
So, if you think there is any other way to speed up the process, I am happy to be informed. Furthermore, I cannot use CUDADot in my MMA. It fails to be fully downloaded and installed after 30 minutes. Any tips to accelerate the process is fully appreciated.
