Scala Option Impact

Asked 2021-Mar-18 at 19:50

I am having trouble with the scala .getorElse command. I want to generate AVec at all times, but I only want AVec and BVec when elemA >= 50, and lastly, I want all of them to be generated when elemA >= 100. I have tried .get with no luck and below you can see the implementation with .getorElse.

Any advice on how to implement this correctly would be greatly appreciated. Thanks!

Why can't you convert containers using .into() if the elements can be converted?

Asked 2021-Feb-24 at 13:27

If I have a Vec I can't convert it into Vec directly using .into() even if I can convert T into U using .into(). For example this code does not compile:

ANSWER

Answered 2021-Feb-24 at 13:27

The issue (currently) with having a blanket implementation for converting containers, is that it conflicts with the existing blanket implementation impl From for T.

To be able to get around that, it would in short require specialization (Issue #31844).

R minimum variance portfolio: solve non invertible matrix

Asked 2020-Sep-30 at 12:20

I want to solve an optimization problem regarding a minimum variance portfolio using R as shortly described on this website: http://enricoschumann.net/R/minvar.htm

The problem is: the matrix I want to use has more columns (=assets) than rows (=observations), which is why it is not positive definite and non-invertible.

You can recreate this problem by taking the opposite values for the variables as on the website, which results in the following:

QUESTION

How do I input signs for constraints without an error message in R

Asked 2020-May-29 at 17:18

I would like to include "signs" in my constraints regarding an LP problem.

For example,

Maximize 120X1 + 230X2 + 410X3 + 100X4

580X1 + 600X2 + 800X3 + 300X4 ≤ 1000

0 ≤ X1 ≤ 10

6 ≤ X2 ≤ 10

5 ≤ X3 ≤ 12

0 ≤ X4 ≤ 10

The code is as follows,

library(lpSolve)

...

ANSWER

Answered 2020-May-29 at 17:18

Note that 580X1 + 600X2 + 800X3 + 300X4 ≤ 1000 makes the model infeasible. This is a very simple textbook LP solver, and does not seem to handle that very gracefully.

QUESTION

R solve.QP tracking error minimization constraints inconsistent

Asked 2020-May-19 at 00:33

I am struggling with Solve.QP to get a solution to minimize tracking error. I have a benchmark consisting of 6 assets (asset_a to asset_f). For my portfolio I have upper and lower bounds (I cannot have a position in asset_f). The cov matrix is also given. I want to get the portfolio weights for the 6 assets that minimizes tracking error vs the benchmark (with position in asset_f equal to zero).

benchmark:

asset_a: 0.3
asset_b: 0.3
asset_c: 0.1
asset_d: 0.1
asset_e: 0.1
asset_f: 0.1

lowerbounds:

asset_a: 0.166
asset_b: 0.133
asset_c: 0.037
asset_d: 0.035
asset_e: 0.039
asset_f: 0

upperbounds:

asset_a: 1
asset_b: 1
asset_c: 1
asset_d: 1
asset_e: 1
asset_f: 0

benchmark weights and bounds:

ANSWER

Answered 2020-May-19 at 00:33

Seems like there is something wrong with your Amat and bvec, i.e. you need not have to pass in both sum of weights on first 5 assets equal to 1 and sum of 6 assets equal 1 and also benchmark weights are not constraints but the bounds are:

QUESTION

SciPy ODE Solver Ignoring function

Asked 2020-Feb-25 at 20:47

I am trying to make Scipy's ODE solver solve the Lorentz Force differential equations. It does not solve the equations correctly with the B-field component because it completely ignores the E-field no matter how large I make it (Which is also why I know it is ignoring it). Why is this? I have already tried modifying the sign on the E-field function too.

Code:

...

ANSWER

Answered 2020-Feb-25 at 20:47

You define P0[2] = 0.. The electric field function computes Ez = 2.8E8*z**4. Hence, python is not ignoring the E-field function, you are putting its z component to zero yourself: z = P0[2] = 0.
