Lecture 15 - Optimization Techniques | Fibonacci Search Method (Part 2)

[@rushkinrenny4524]

Sir, why length is constant? Because on each iteration range become reduce so length become also reduce.

[@SukantaNayakedu]

Please see the discussion in others comments. Same thing has been discussed.

Hindi language me nHi hai kya sir

[@SukantaNayakedu]

Bas 5 video hai

[@shreyashsachan321]

Why you start solving problem with k=2

[@SukantaNayakedu]

Please see video, first part of Fibonacci Method. The doubt may clear.

Sir for max. Of objective function how to solve??

[@SukantaNayakedu]

Change the objective function. Minimum of f(x) is maximum of -f(x).

[@sohamkamtikar2794]

Is F4 value is 3 or 5 sir

[@sathwiknallagundla]

Why did you took that k=2 for itration 1 and k=3 for itration 2 ??

[@himanshud2611]

cuz in algo k=k+1 in each iteration

[@mathiharan8109]

sir for a similar question...I'm getting f(x1)=f(x2) at the 3rd iteration....what to do?

[@SukantaNayakedu]

Then take anyone and continue the search.

@@SukantaNayakedu Thank you sir for the quick response!!

[@R4W_Pallavi]

Thanku sir this video helps me alot

[@SukantaNayakedu]

All the best...

In iteration 2 the value of a=2 , b=5 and the value of L will be (b-a)=3 .why you use 5

[@SukantaNayakedu]

In this method, L will be treated as constant.

[@MusicLover-ox9fk]

If in the 2nd iteration the value of a and b changes then the value of L=b-a should also be changed.. So why we are putting L=5 i.e(a=0,b=5) in case of finding Lk*.. And putting a=2,b=5 in case of finding x1 and x2...

[@SukantaNayakedu]

Refer kalyanmoydeb book for optimization, you may understand. But in SS Rao optimization book L changes with different algorithm. Anyway the method should valid in the sense of converging answers (solutions obtained in iteration)

[@mouleshm210]

why n is taken as n=3? and why do we always start with k=2?

[@beoptimistic5853]

[@keshavniketh7060]

after the first iteration should we update the value of L or not??

[@SukantaNayakedu]

L will be same for all the iterations.

[@RajwinderKaur-xq2dn]

Sir k ki value kaise lii hai

[@SukantaNayakedu]

K value depends on the Fibonacci numbers. Also, first two Fibonacci numbers are same, that is, 1 and 1. Zeroth Fibonacci number is 0.

[@varunpratap6785]

why L is constant throughout in this method whereas in all other methods L varies as 'a' &'b' changes

[@SukantaNayakedu]

Nice question. To mentain a regular pattern of elimination of region, L is constant here. Also, it will be helpful to observe the convergency of this method. You may easily verify by taking updated L and constant L. Thank you.

[@keshavniketh7060]

@@SukantaNayakedu didnt understand properly? the total meaning of region elimination is to eliminate the "not recquired region" then how come constant L will solve the problem

[@SukantaNayakedu]

This is because if L varies then it may affect the convergence. Also, L value will not hamper the elimination region rule.

[@farazahmad4467]

Dought... Read carefully... L2*=(Fn-2/Fn)L0 Or Lk*=(Fn-k+1/Fn+1)L Which one is correct formula?

[@farazahmad4467]

Please give me answer

[@pranaydas4235]

Why k=2 in 1st iteration?

[@SukantaNayakedu]

First two Fibonacci numbers are same.
