graphs – Finding the smallest-cost way to deliver goods

I want to deliver products from various sources to various destinations such that the overall cost is minimized. However, each supplier (“source”) has a contractual obligation: they specify a minimum and maximum quantity of the product that should be taken from them (i.e. the “minimum” indicates that one must purchase at least that amount, whereas the “maximum” indicates that we must take no more than that amount).

My manager tells me that they have computer code that can solve the capacitated minimum spanning tree problem (see: https://en.wikipedia.org/wiki/Capacitated_minimum_spanning_tree). Using this as a oracle, how can you determine a method to determine which supplier(s) should deliver their products to which destination(s) at a lowest total cost (or explain why it can’t be used to solve the problem)? I’m provided with the costs $c_{i, j}$ of transporting from source $i$ to destination $j$, and I’m also provided with the minimum and maximum quantities of product to be taken from each supplier.


This is a practice problem that I encountered while studying NP completeness and reductions.

I know that I need to somehow construct a graph to pass into the blackbox but coming up with the graph is the tricky part. I thought about constructing a graph with all of the $c_{i, j}’s$ as edge weights, but then I can’t get the maximum and minimum quantities to come into play. I’ve thought about this problem for a while now, but I still can’t figure it out. Does anyone have any suggestions? This reduction seems a lot more complicated than the other ones I’ve seen, or maybe I’m just overthinking it?

database – Tool for goods overview for employees

I’m looking for a tool that will help me create a very simple editable sort of (web)app-thing, which will work as shown on this image. I don’t know how to call such a thing, hence I have to describe it.

Basically the first screen shows 5-10 small icons-windows (A-J), all of them are hypertext links. When you click one of them (B in the image), you are taken to a different screen which could contain either another sort of junction like the first screen (B1-B20), or it could contain some final screen with desired information.

The idea is, that the company makes goods and ships them to multiple countries, but the goods and packing directions differ. The created app would allow employees to easily find what goods ship to which country and how they should be packaged.

So the first screen would contain country flags/names (A-J). After clicking on a country, you would be either taken to:

  • or a screen with goods and their packaging info for that specific country
  • a screen with said countrys regions (B1-B20) if goods and packaging differ by region and those region windows/icons would then take you to the final screen mentioned above

I know this is easily created in powerpoint with hypertext links, but this solution is not ideal, as it’s not that easily accessible at anytime from anywhere. A web app seems ideal.

I would be able to create this with my basic HTML/CSS/JS knowledge, but my skills aren’t good enough to create an administration for this app and the company would be dependant on me for editing the information, which isn’t good. It would be best if a manager could easily edit the information.

relocation – Moving to Canada – Do I need to be physically present when household goods arrive in Canada?

I am currently talking to movers to move my personal items/household goods from Hong Kong to Canada (I will be studying in Canada as non-Canadian/non-PR). I will be flying to Canada around the same time as the moving of my items and hence will arrive in Canada well before my personal effects arrive by sea freight. The freight will go to Vancouver, BC, but I will by the time the items arrive already be studying almost 1000km away from Vancouver.

One particular mover, whose service I like and whom I have used before, insists on me having to be personally present when my shipment arrives in Vancouver and undergoes customs clearance. I have never heard of such requirements and it would be a major inconvenience to travel 2000km (two-way) just so I can be physically present at the port of entry of my personal effects. The entire point of using a door-to-door service is to avoid such hassle.

Can someone share from their personal experience or point me to a federal document that states such requirements should it really exist?

Thanks
Matt

General guidance on pricing goods, services, and balancing economy [closed]

As I’m making my way through a campaign, I’m beginning to realize that I don’t know what to do about money. My tier 2 (out of 6) players have 200 shins (gold in Numenera terms) between 5 of them, we don’t know if that’s a lot or a little, and we stopped caring about money altogether – finding monetary rewards is not exciting, and money is not a motivator. I’m trying to price and offer some goods and services — which will create the desire for players to spend (and acquire) wealth.

Is there some generic guideline against which I can use to price things? I think I just don’t have a good gut feeling how to price hiring a group of guards or a spy for a month vs a sack of grain or price of a sword.

How do I begin to estimate price of goods and services? Are there good resources to help me?

game theory: trust in online platforms that deal with virtual goods

Hope this is the correct stack swap for these types of questions. It can probably be more generalized, but I'll explain it using my use case.
I am implementing an online platform, where third parties sell virtual products to customers by subscription. Take e-books for example as a virtual good in this case.
How can third parties trust my platform? How can they know that I am not cheating with the number of subscriptions that I inform them? Are there solutions for this or some documents? I can't be the first with this kind of problem. The problem is, I don't even know what to look for.
Game theory is also the only tag I can think of, maybe someone could edit the tags?

Thanks in advance

c ++ – Maximize the value of goods in a triangular container

In this task, you should find the best solution for the given problem.

They give you
METER – ship's capacity where it can store items with heights less than I-the height, for example, in the first place you can store only elements with height 1, but in the second place you can store elements with heights 1 or 2.
north – number of elements. Each element has two taxes: height and value. We want to maximize the sum of values ​​of the elements taken.

#include 
#include 

#define INF 10000006
using namespace std;

long long getint(){
    char c;
    long long temp = 0;

    do{
        c = getchar_unlocked();
    }while(c < '0' || c > '9');

    do{
        temp = temp * 10 + c - '0';
        c = getchar_unlocked();
    }while(c >= '0' && c <= '9');

    return temp;
}
struct panel {
    long long value;
    long long height;
};
bool comp (const panel &a, const panel &b){
    if(a.value == b.value)
        return a.height < b.height;
    return a.value > b.value;
}

panel tab(1000020);
long long tree(1500020);
long long taken;
panel temp;
unsigned long long score = 0;
long long powerOfTwo = 1;
long long height;
long long treeLast = 0;

void addToTree(int a){
    tree(a) = INF;
    while(a != 1){
        a /= 2;
        tree(a) = min(tree(a * 2), tree(a * 2 + 1));
    }

}//dodaje wartosc inf w wierzcholku /A added value inf in vertex A
int look(int x){
    //powerOfTwo first index on the tree
    while(x < powerOfTwo){
        if(x * 2 >= powerOfTwo && x * 2 < treeLast){
            x *= 2;
            if(tree(x) == 0){
                addToTree(x);
                return 1;//succeeded
            }
            else if(tree(x + 1) == 0){
                //cout<<"look"<

My idea for that task is the greedy classification and then choose the best items if we can store them in our boat. The complexity of the solution is good O (n * logn), but sometimes I get WA (Incorrect answer). If you can verify the style of my code and maybe find some error / counterexample.
