sir sahi me itna simple bataya super maine bahut chamnnel mi video dekhib par wo solving method difficult thi apne padhae wo bahut hi simple he

Thank you sir I was very confused that how can I write it in exam step by step.

[@aidenpierce2421]

Can you please make a video on Fractional knapsack, knapsack with dynamic programming.

[@jainamshah6202]

6-2 ke baad zero hi Q aana chahiye?

[@OctopusBaba]

4th line main hi 0 Q krna hai, reason do wrna samj kaise ayga

[@Anonymous-vk7ig]

bag poora ful karna hai jiske wajha se capacity 0 ho jayega, to usse hisab se jitna weight bacha hai uss bache hue weight itna hi profit milega

[@bgmiislive_]

Bhai uska toh placement ho gya pr itnii jaldi reply dediya tune use ​@@Anonymous-vk7ig

[@akashrane1691]

Best Explanation Ever sirG

[@zahidshaikh2988]

Sir agar last me we are getting a object with last same remaining weight we have to direct do subract and get zero. Or we have to take ratio of the profit.

[@Anonymous-vk7ig]

sir in college exam we have to show all 3 step if the question is of 7 marks??? i have also watched gate smasher video he saaid that only p/w is necessary.

Last method is best and mostly used in knapsack algorithm

4:06 when will we know to take remaining weight as zero

[@md.farzan5596]

The value of M after filling the bag will be 0.

[@nikitavairagade7734]

Sir maximum profit solve krte time agar 2 jagha profit ki value same hai tho kaise krege

[@EasyEngineeringStudies]

fir apko object ka sequence follow karna hai... consider this example only there are 7 objects in all. usmay se agar object no 4 or 7 be profit value agar same hai. so first object you will consider is no 4 then 7...This thing you have follow all profit, weight and pi/wi ratio agar same values atte hai always see for sequence of object that will be always 1 to 7 or any no of objects given in question.

[@tejaspatil3978]

sir , this knapsack and fraction knapsack same or different..?

[@MadhushreeDoshi]

There are two types of knapsacks, 0/1 Knapsack and Fractional Knapsack. Fractional knapsack has been used in this video. The key difference between 0/1 Knapsack and Fractional Knapsack is that, in 0/1 Knapsack you are not supposed to fill the container/bag with a part of object. i.e either full object will go or no object, but in fractional knapsack you can put a fraction of object in the container/bag. 0/1 knapsack is generally solved using dynamic approach.

[@souravbhagat1358]

Please upalod more videos ..

[@md.farzan5596]

Sir aapne select object with maximum profit waale method: me last me profit 7 hai or aapne four liya hai. To ye to n ki value ke against hai?

[@md.farzan5596]

I think 7/10*4 yaani 2.8 hona chahiye.

[@pradnyapardhemoon8811]

please explain the dijkstra algorithm

[@gouravpradhan1502]

is it essiential to perform all the three steps?

[@EasyEngineeringStudies]

yes After performing all three steps only you will be able to know which is the best method..becoz we have only three 3 things we can check i.e 1.Pi 2. Wi 3. Pi/Wi...

Very nice

[@no.14devashrigiri81]

Thank you 🙏

[@manisharastogi2459]

Plz tell why....how you will chose ratio in last line of method 2nd 3 I didnt get..reply as soon as possible plz... tmrw is ppr

[@EasyEngineeringStudies]

I forget to mention the object in method 2..The last object is Object no.3 and Its WI (weight) value is 3 that is less than remaining weight that is 4. So you will do 4*3=12.....Remember one more thing if Wi value would have been greater than remaining weight than you have to use Ratio value of that particular object otherwise use the Wi value if it is less than remaining weight.

[@EasyEngineeringStudies]

hope you got the answer..And best of luck for exam.

[@EasyEngineeringStudies]

And always remember for all example of knapsack..To use the value of Ratio there is a condition that the value of Pi or WI given in question should be greater than remaining weight of second last step. if it is not greater than remaining weight don't use ratio value for last step. Use original value of PI or WI.

[@manisharastogi2459]

Not getting still....but no problem...thanx

[@vehiclelegacy1594]

Sir in exam can we solve this question by any of the above 3 methods? Or we have to use all methods?

[@vimalthekkan7026]

not necessary to use all. its okayy even if you use only the ratio method

[@uastudymates5555]

Thank you bhai

[@Pooja-ki9om]

Sir hmay y kasy pta chlega ki remaning weight m konse stage aaney pr zero lana h... Knapsack example say related h

[@EasyEngineeringStudies]

In this question capacity given is 15...That is you start remaining time with 15...As you have to solve this question in 3 methods...1st method may apko dekhna hai maximum profit, that is you to see from high value of PI to low value.So at one stage, there will be the reaming time, jo apko zero answer dega..Second last step is 6-2=4, abhi hamera pass reaming time hai 4...So next object jo select karoge wo hai 4 par uske PI ke value hai 7, jo greater hai reaming time se.. So you have to use pi/wi value jo hai 1..isse liye pi ke value ho jayege 4*1=4 in table, wi ke value bhi 4 or remaining time hoga 4-4=0...so you have to solve all methods like this.

Just send me your mail id I will send you some examples for all remaining topics... I will tell you the trick for 4 queen and 8 queen problem and other topic examples I will mail you. Do 1 thing for 4 queen and 8 queen If you are allowed calculator store all the sequence in your calculator( There final answer that is sequence you write for 4 and 8 queen). one example below of 4 queen 1 2 3 4 1 --- --- Q1 --- 2 Q2 ---- ---- ---- 3 ---- ---- ----- Q3 4 ---- Q4 ---- ---- So its sequence will be ( 3,1,4,2) You have to see the column and the write the above number since its 4 queen problem and same thing for 8 queen also.... Now store all the examples sequences that you have with you for reference in to your calculator so that when you solve this example in exam you will have the sequence for question asked and just you will have to make the table and write Q position according to sequence you stored....

[@amitsaha3858]

❤

[@BhaveshSinghBhanucsgo]

Har table ka last step kaise krde rhe ho yaar

[@EasyEngineeringStudies]

bhavesh I will explain you.... method1: aisa object select kar hai jiska sabse highest profit hai,wo object hai 6 or uska profit hai 18..or iska weight hai 4..so complete capacity de hai 15. so you have minus 15-4=11...after this same for remaining object till object no 1... .now you have problem here..as you have to solve from highest profit to lowest profit or sath may uska weight bhi minus kar rahai ho.. .so object no.1 ka profit tha 10.ab iska baad next lowest profit hai 7 or wo object hai 4 or iska weight hai 7 ..par abhi hamare pass remaining weight hai 4..jo 7 se less hai..so in such case apko object no 4 ka ratio multiply karna hai remaining weight se jo milta hai 4 or weight block may bhi remaining weight use karna jo hai 4 issliye at last 4-4=0..bas isse tara se solve karna hai baaki table.
