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.

[PYARAKAPUSHYAMITHRA]

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

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

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

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

[shibammajhi]

Sir I think you are the busiest person in the world 😢. Please be slow a little bit 😢. My mind got blocked when I saw your lecture 😭

[_anshvarma]

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

[nomanrajput]

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

[edugk]

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).

[GauravThelkar]

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

[nahiduzzaman]

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

[marcellacella]

Thank you for the clear explanation sir

[akileshmurali]

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?

[kumarjarajapu]

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

[MS_Saroj-World]

If n is not given in the question then??

[edugk]

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

[HarshilKathiriya-so]

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

[rajdeeppaul]

Sir please, teach in Hindi, you are very bad on Engrish, pls dont

[ig_sussybaka]

Sir Hinglish mei mt pdhao, english mei pdhao
