问题 This question already has answers here : How to find which elements are in the bag, using Knapsack Algorithm [and not only the bag's value]? (4 answers) Closed 6 days ago . I know how to solve knapsack 0-1 problem with dynamic programming approach, but I am having troubles figuring out which items to take without compromising the complexity of O(N * C) (N items, C capacity). Any ideas (I would prefer a bottom-up approach)? 回答1: Suppose, right now you're storing results in array bool[] a ,

问题 I am exploring https://github.com/umano/AndroidSlidingUpPanel library. When I slide the bottom panel, on slide complete it acquires complete screen area. Can anyone help me, How to stop the bottom panel to a certain height, for e.g. slide it till middle of screen?? 回答1: Have you considered using setAnchorPoint(float) ? From the DemoActivity in the SlidingUpPanelDemo project SlidingUpPanelLayout layout = (SlidingUpPanelLayout) findViewById(R.id.sliding_layout); layout.setAnchorPoint(0.3f);

Grammar: difference between a top down and bottom up? (Example)

问题 This is a follow up question from Grammar: difference between a top down and bottom up? I understand from that question that: the grammar itself isn't top-down or bottom-up, the parser is there are grammars that can be parsed by one but not the other (thanks Jerry Coffin So for this grammar (all possible mathematical formulas): E -> E T E E -> (E) E -> D T -> + | - | * | / D -> 0 D -> L G G -> G G G -> 0 | L L -> 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 Would this be readable by a top down and

问题 How can I return an arbitrary XML document using an Eclipse/AXIS2 POJO Service? For full background details, see this question: Java Web Service returns string with > and < instead of > and < To deploy the web service, I have a dynamic web project with a class that defines the interface of my service. The method I am concerned with returns a String type. To create and deploy the web service I right click on the class (contained in the dynamic web project) and select create web service, here I

Dynamic Programming - top-down vs bottom-up

我们两清 提交于 2019-12-11 03:03:15
问题 What I have learnt is that dynamic programming (DP) is of two kinds: top-down and bottom-up. In top-down , you use recursion along with memoization. In bottom-up , you just fill an array (a table). Also, both these methods use same time complexity. Personally, I find top-down approach more easier and natural to follow. Is it true that a given question of DP can be solved using either of the approaches? Or will I ever face a problem which can only be solved by one of the two methods? 回答1: Well

Grammar: difference between a top down and bottom up?

问题 What is the difference between a top down and bottom up grammar? An example would be awesome. 回答1: First of all, the grammar itself isn't top-down or bottom-up, the parser is (though there are grammars that can be parsed by one but not the other). From a practical viewpoint, the main difference is that most hand-written parsers are top-down, while a much larger percentage of machine-generated parsers are bottom-up (though, of course, the reverse is certainly possible). A top-down parser
