Abstract In a classical k-min search problem, an online player wants to buy k units of an asset with the objective of minimizing the total buying cost.

After receiving the price quotation, the online player has to decide on the number of units to buy. The objective of the online player is to buy the required k units in a fixed length investment horizon. Online algorithms are proposed More >
