build the map. Each map is set up with a super source point connected to all the suppliers, and the capacity is the inventory of the supplier I Commodity

, the cost is 0, each supplier is connected to all stores, the capacity of the INF, the cost of the supplier to the corresponding store to send the cost of goods I; Finally, set up a super meeting point, so that all stores to the meeting point, capacity for the store's demand, the cost is 0; Then ask for the K-th minimum fee,
The GROUPING function can accept a column and returns 0 or 1. If the column value is empty, GROUPING () returns 1; if the column value is not empty, returns 0. GROUPING can only be used in queries using ROLLUP or CUBE. GROUPING () is useful when a value needs to be displayed in the return of a null value.
1. Use GROUPING () for a single column in ROLLUP ()

attributetypes
Attributetypes is equivalent to the table attribute in the database. Unlike the database, one record and one attribute can have multiple values.Attributetype Syntax:Attributetypedescription = "(" WHSPNumericoid WHSP; attributetype identifier["Name" qdescrs]; name used in attributetype["DESC" qdstring]; Description["Obsolete" WHSP]["Sup" woid]; derived from this other; Attributetype, if there is no
method determines whether t contains this set of items, and if so, outputs a key-value pair (key=, value=1). Reducer summarizes the key-value pairs for all the same key (that is, the candidate), re-evaluates the candidate's life cycle, and determines whether the total support count is not less than the minimum support level. If so, he outputs a key-value pair (key= the candidate, Value=sup (I,lifetime (i)), ALGORITHM5 gives the specific algorithm:4.2
CSS reset refers to the style of resetting the browser. In various browsers, the CSS selector will default some values, such as when the H1 is not set to a value, display a certain size.But not all browsers use the same values, so CSS Reset is used to make the style of the Web page consistent across browsers.Here are a few of the main CSS reset codes:1.

Topic:
There is a tree, each node weights w[i], choose a node to blow up, and the node distance w[i] Other nodes within the site will also be blown up. Choose at least a few nodes to blow up the whole tree.
Method:
Definition Up[u][i] means that you can blow up a subtree of u, and you can blow up the nodes within the distance of I.
The definition Down[u][i] represents a subtree in U, and the presence of a point of depth of I has not been blown.
1: Do not blow
