    Amazing video. Explaining with an example helped me skip through the thory and directly understand the problem by solving the problem. Thank you !

    At 14:01 For (Gbest - Xi) , It should be (1.25-1.88)
    At 14:37 , Initial Velocity that we found in the last iteration was 0 but here you write 0.2583 and in all steps for finding updated X you added it with velocity but here you subtracted (1.25-0.2666)
    Please explain this.

      At 14:01 Gbest = 1.25 so yes you are write , It should be (1.25-1.88)
      At 14:37 - for 2nd iteration: we are using updated velocity instead of 0

      @@RitikaxRayPixy could you explain how have you updated the velocity from 0 to 0.2583
      ?

      By Using velocity update formula.

    At 14:21 how u have taken v3 is 1.153 becoz at 1st u have calculated v3 as 0.153
    And also at 14:30 u have taken v4 as 0.2583 and also u have calculated at 1st v4 as 0

      05:30 Initial Velocity = 0
      08:09 New Velocity Calculate (3.3825 for X1) and so on for all particles
      Iteration 2
      13:24 velocity Calculated (3.489 for X1) and so on

    There are too many errors in your video, at 14:21, the previous v was 0.1537 but you set it to 1.1537 and the same error in x4. And why do you always use xi - vi for x4 ? Hope you reply soon, thank you

      @RitikaxRayPixy  6 місяців тому

      Thanks for your feedback. Yes, we accidently type 1.1537 ( use 0.1537). For all particles when we will update position we will add velocity in their older position. For x4, kindly use (1.25 + 0.2066)

      @@RitikaxRayPixy thank you for your response. Actually I have a problem regarding geotechnical engineering. I have data regarding the bearing capacity of soil. There are a few input parameters on which the bearing capacity of soil depends. Dear ritika, I just wanted to know how I can optimise this problem? I mean what should be my inputs for the different particles. Or simply how can I approach this problem? Hope to hear from you soon. Thanks and regards
