Abstract
A first module acquires a plurality of transaction conditions each including a plurality of items, from a plurality of terminals corresponding to a plurality of users via a network, a first memory device stores the transaction conditions acquired, a second module generates several combinations of the transaction conditions stored in the first memory device based on the items of each of the transaction conditions, a second memory device stores the combinations, and a third module presents each of the combinations stored in the second memory device to several of the terminals which involved in the each of the combinations by submitting one of several of transaction conditions is included in the each of the combinations.
Claims17
An electronic transaction mediation method comprising:
- acquiring a plurality of transaction conditions each including a plurality of items, from a plurality of terminals corresponding to a plurality of users via a network;
- storing the transaction conditions acquired, in a first memory device;
- generating several combinations of the transaction conditions stored in the first memory device based on the items of each of the transaction conditions;
- storing the combinations, in a second memory device;
- and
- presenting each of the combinations stored in the second memory device to several of the terminals which involved in the each of the combinations by submitting one of several of transaction conditions included in the each of the combinations.
An electronic transaction mediation apparatus comprising:
- a first module which acquires a plurality of transaction conditions each including a plurality of items, from a plurality of terminals corresponding to a plurality of users via a network;
- a first memory device which stores the transaction conditions acquired;
- a second module which generates several combinations of the transaction conditions stored in the first memory device based on the items of each of the transaction conditions;
- a second memory device which stores the combinations;
- and
- a third module which presents each of the combinations stored in the second memory device to several of the terminals which involved in the each of the combinations by submitting one of several of transaction conditions included in the each of the combinations.
A combination generating method comprising:
- (a)generating a plurality of combinations of a plurality of conditions each including a plurality of items;
- (b) storing the conditions in a first memory device;
- (c) linking each one of the conditions stored in the first memory, to other conditions stored in the first memory device, at least one of the items of each of the other conditions meets at least one of the items of the one of the conditions;
- (d) selecting a first condition of the conditions, to obtain a root node of a search tree;
- (e) generating a plurality of first subsets, each element of each of the first subsets is an element of a set of conditions linked to the root node;
- (f) connecting each of the first subsets to the root node as a node of the search tree;
- (g) generating a plurality of second subset, when one of the node of the search tree having a plurality of elements, each element of each of the second subsets is an element of a set of conditions each linked to at least one of the elements of the one of the node;
- (h) connecting each of the second subsets to the one of the node as a node of the search tree;
- (i) repeating step (g)-(h) until a given convergence condition is satisfy, to obtain the search tree;
- (j) generating a plurality of combinations of the conditions stored in the first memory device, by adding each element of one of a child node of the search tree to a set of conditions corresponding to a parent node to which the child node is subordinate.
