Multi-level bartering loop

A method for implementation of a multi-level bartering loop, comprising:

• receiving, by a multi-level bartering loop (MLBL) server node, a barter request comprising a selected item from at least one user device;
• retrieving, by the MLBL server node, a record of the selected item from a pre-built graph table;
• placing, by the MLBL server node, the record into a path vector and adding the path vector to a queue;
• responsive to the queue being not empty, shifting, by the MLBL server node, the path vector into a current path vector from the queue, wherein the shift comprises load and remove first action;
• loading, by the MLBL server node, last item's reference from the current path vector and retrieving a record corresponding to the last item from the pre-built graph table;
• responsive to the record corresponding to the last item containing at least one accepted item, comparing, by the MLBL server node, the at least one accepted item to the selected item;
• and
• responsive to a match between the at least one accepted item and the selected item, reversing the current path vector by the MLBL server node.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• receiving a barter request comprising a selected item from at least one user device;
• retrieving a record of the selected item from a pre-built graph table;
• placing the record into a path vector and adding the path vector to a queue;
• responsive to the queue being not empty, shifting the path vector into a current path vector from the queue, wherein the shift comprises load and remove first action;
• loading last item's reference from the current path vector and retrieving a record corresponding to the last item from the pre-built graph table;
• responsive to the record corresponding to the last item containing at least one accepted item, comparing the at least one accepted item to the selected item;
• and
• responsive to a match between the at least one accepted item and the selected item, reversing the current path vector.
