QUESTION
I have a piece of code that worked well when I optimized advertising budget with 2 variables (channels) but when I added aditional channels, it stopped optimizing with no error messages.
...ANSWER
Answered 2021-Dec-05 at 11:43The reason you are not able to solve this exact problem turns out to be all about the specific coefficients you have. For the problem as it is specified, the optimum appears to be near allocations where some spends are zero. However, at spends near zero, due to the negative coefficients in media_drs
, the objective function rapidly becomes infinite. I believe this is what is causing the issues you are experiencing. I can get a solution with success = True
by manipulating the 6.7 to be 0.7 in the coefficients and setting lower bound that is larger than 0 to stop the objective function from exploding. So this isn't so much of a programming issue as a problem formulation issue.
I cannot imagine it would be true that you would see more payoff when you reduce the budget on a particular item, so all the negative powers in media_dirs seem off to me.
I will also post here some improvements I made while debugging this issue. Notice that I'm using numpy arrays more to make some of the functions easier to read. Also notice how I have calculated a correct jacobian:

QUESTION
I'm writing a musical gallery using vanilla javascript. Each photo plays a different song onclick
.
Currently each click starts the song again in the background, so it can play as many times as clicked on. Also, all photos can play simultaneously.
I'm trying to figure out how to get only one song to play at a time and restart onclick
rather than play over itself.
I think the way to do it is to get the last click event and then audio.pause()
all other songs but can't seem to figure out quite how to do it, would love some help.
Thanks!
ANSWER
Answered 2021-Jul-09 at 04:08You could scope your audio player outside of your function. You could then check to see if audio.paused
is false to see if a song is currently playing, and pause it before changing the src
.
QUESTION
I am trying to cythonize my Python code to improve performance.
I didn't make any change to my original python code, I just run the setup.py
and get the .c files.
Now I have this issue: when I perform a basic math operation in Python, it works fine, while in Cython it doesn't work as expected.
The code snippet is the following, here I try to calculate the y-coordinate of a given x on a circle of center [3,0] and radius 1:
...ANSWER
Answered 2021-Jun-12 at 08:42I suspect that cdivision=True
is enabled inside your setup.py
. In C, the division of two integer literals cuts off all decimal places. Consequently, the 1/2
inside your return statement equals 0.0
. Instead, simply use floating-point literals, i.e.

QUESTION
I wanted to add "transparency" to my Game Engine, which I have no earlier knowledge of. I didn't find any straight answer on how to implement it so I ended up doing some research about something called Alpha Blending which is one way of showing opacity if I have understood it right.
I Googled around and tried to find a source that showed how to implement this when you have a pixel array. I have no clue how but I found nothing except a tutorial on Youtube. They didn't explain why they did like they did and due to that I still have no clue how I can implement it or how it works. I tried to follow the tutorial but the code they used didn't work at all so I changed it a bit (which clearly didn't work).
This code below is my setPixel() function that sets a pixel at a specified location. From the start of the function it just checks if it needs to place a pixel at all. This function is used to draw every individual pixel from the pixel data. The pixel data of the screen is stored in the variable pixels. The image data is stored in value. Value is however just an integer, while pixels is an array..
