Golden Section Search Method for Unimodal Functions

[@amirah_sri]

To all the having doubt that why 0.618 is taken instead of 1.618 :
It is because in the beginning of the vedios while sir was explaining the equation has 1/golden ratio (r)
1/1.618 = 0.618

[@explorewithutsav]

Great teaching but I wonder if it really has any sense in real world?

[@rameswarpradhan7692]

It is applicable bro in life

[@vishwasdeshpande3921]

In engineering science,nothing can move without optimization! Any problem can be converted in to constrained or unconstrained objective function of n variables and solved by numerical methods.
May I bring your attention to how " Nature" & "Optimization" are related?
Think of " 🌻 Sunflower seeds or Sea 🐚 shell. Fibonacci numbers can explain how these are evolved.
Excellent presentation Dr Garg

[@nomanrajput298]

That was so helpful! I just started using soft and was so overwheld!

[@020_anshvarma5]

Sir u used 0.618 as golden. Section ratio in the questions is this correct or we should use 1.618

[@mathematicsworld5783]

Great sir, best way to express

[@DrHarishGarg]

Thanks for the appreciation

[@GauravThelkar]

thanks Sir... can you please add Binary Search type for the Line search algorithm... if already covered can you please share the link

[@taruchitgoyal3735]

Hello Sir,
At 19:45, can you please share how did you compute the value of f(x*)=0.19430?
And how did you compute the values for Emin?
Thank you

[@_poke_rock]

I think this is wrong i mean value of x* is correct but f(x*) should be -0.5623

[@PYARAKAPUSHYAMITHRA]

x* calculation error at the end it should be 0.28 at 15:24

[@maazshaikh5283]

I think it should be 0.58

[@edugk30]

All your lectures are very much useful for us sir.Thank you for your support sir.
I have one doubt sir, will you please share if there is a link for solving (arithmetic and geometric mean inequality), and (primal dual relationship & sufficiency conditions in the unconstrained case).

[@kitebaaz]

f(x^*) in all cases is calculated wrong. Do your own calculations. x^* in 3rd ques is also calculated wrong. Rest the lecture is explained nicely!! Thanks Sir.

Thank you ❤

[@lordcasper3357]

you are a hero

[@Indian_5278]

Kamal Hai sir keep going

[@DrHarishGarg]

Thanks for liking.... Watch their matlab code video too And other lectures

[@sagnikdash9060]

Thank you so much sir

[@marcellacella8293]

Thank you for the clear explanation sir

[@pahadinegi006]

what we use0.618 or 1.618

[@kumarjarajapu1605]

Sir, is this method also called BROYDEN FLETCHER ?
If not can you drop the link please?

[@DrHarishGarg]

No....."BROYDEN FLETCHER" method is different from this Golden Section Search

[@kumarjarajapu1605]

@@DrHarishGarg ok sir

[@nahiduzzaman5691]

Where is the video for MatLab code for Golden Section Search, I cannot find it

[@DrHarishGarg]

Will upload soon.

[@MS_Saroj-World]

If n is not given in the question then??

[@rishabhrana1914]

thankyou sir

[@luckystechentertainments5601]

great sir....😇😇

[@DrHarishGarg]

Thanks. .. My pleasure.

[@akileshmurali3848]

at 6.56 minute of video how the this step obtained
Ik/I k+1 = Ik+1/IK+2 =c ( Constant) for all k could you please explain this?

[@priyanshugupta4328]

there is no equal to sign , between Ik/I k+1 = Ik+1/IK+2 , it's multiplication in which I k +1 can be canceled further and eqn remains same.

[@edugk30]

Respected sir, what is the difference between Fibonacci method and Golden section method by using table calculation.

[@DrHarishGarg]

Dear... It is already mentioned in the lecture as well in the lecture of Fibonacci search method lecture.... See the number 0.3..is constant for Golden section however it is varied in Fibonacci

[@edugk30]

Thank you sir

[@nikhilgiri9130]

Simplify your teaching.

[@HarshilKathiriya-s7o]

1st example last calculation goes wrong sir
Also last exampl's calculation goes wrong

[@ALAMIN-n2i6s]

so quick, please take rest

[@pahadinegi006]

ahut confusing pda ra h

[@humariduniya5235]

Very long calculation
