I have to optimize some variables over some data which is quite large, 100MB csv file, one option is to import it in the optimization function, but in this way everytime genetic algorithm has to run the function it will have to load the data which will take extra time, how could i load data once and then genetic algorithm uses it on every instance withload loading again and again.

Hi Haris,
To efficiently use a large dataset in MATLAB while running an optimization algorithm like a genetic algorithm, you should load the data once and then pass it to the optimization function without reloading it each time. Here's how you can achieve this:Steps to Optimize Data Handling
  1. Load the Data Once: Load your CSV data into MATLAB just once before starting the optimization process.
  2. Use Nested Functions or Anonymous Functions: Pass the loaded data to the optimization function using nested functions or anonymous functions. This way, the data remains in the workspace and is accessible by the optimization function without reloading.
  3. Define the Objective Function: Ensure that your objective function can accept external parameters, such as the loaded data.
Hope this helps.
