Some problems which can be solved using dynamic programming are:

111: History Grading

147: Dollars

231: Testing the CATCHER

348: Optimal Array Multiplication Sequence

357: Let Me Count The Ways

497: Strategic Defense Initiative

562: Dividing Coins

674: Coin Change

711: Dividing Up

10032: Tug Of War

10081: Tight Words

10304 Optimal Binary Search Tree

10405: Longest Common Subsequence

10465: Homer Simpson

10482: The Candyman Can

10549: Russian Dolls

10558: A Brief Gerrymander

348, 10405, and 562/674 are fairly classic DP problems - at least one, if not all of them, will probably appear in any text that discusses DP. So one of these might be a good starting point. If you're looking for something which isn't quite as straightforward, perhaps try something like 497 or 10032. More challenging ones are 10304, 10549, 10558.

Aother very interesting dynamic problem is 116.

you can find a list of dynamic problems and many other subject oriented problem list on the site http://www.acmbeginner.tk

Sorry, but those webs are not available !

I'm trying to solve all those problems, and I have done about 60%. Those remains are very difficult to me... so I want to do more problem easier than them. Can anyone help me???

hi friends.

I began to try to solve some DP problems, too.

And I got AC some problems.

Problems that I was able to get the correct answer easily are follows.

103

10069

10405

I think 103 is the most simple DP problem.

And 10069 is same as above.

But to solve this prolme needs BigNumber. You should use your library for BigNumber.

If you use matrix for 10069, you will get (or maybe not) MemoryLimitExceed, so you have to use array.

And the problem 10405 is not easy to solve for me.

But I got understand LCS, problem became easy. This problem is a simple LCS problem.

If I can find other easy DP problems, I will post replay.
