Abstract: Provided is an electronic apparatus and an operation method thereof for, based on location information on a vehicle on a first occupancy grid map, identifying a second occupancy grid map having a first location as an origin and identifying an occupancy state of a grid included in the second occupancy grid map, updating the occupancy state of the grid included in the second occupancy grid map based on information acquired from a sensor, identifying an inflation range corresponding to a first grid among grids included in the second occupancy grid map based on appearance information on the vehicle, and identifying an inflated occupancy state of a second grid included in the inflation range based on an occupancy state of the first grid.

Abstract: Provided is a method of determining a mission of a device in an electronic device, including identifying external situation information and status information of a plurality of devices, identifying an object function related to a degree of fitness of a device for a mission, for each set of a plurality of solutions of a first generation for the plurality of devices, calculating a value of the object function using the external situation information and the status information, based on the value, determining a set of a plurality of solutions of a next generation for the plurality of devices through a genetic algorithm (GA), and based on a first solution from a set of a plurality of solutions of a second generation by repeating the calculating the value and the determining the set of the plurality of solutions of the next generation, determining a mission for the plurality of devices.

Abstract: A dielectric based metasurface hologram device includes: a substrate layer provided at a lowermost portion of the dielectric based metasurface hologram device; and a dielectric layer forming a geometric metasurface on the substrate layer. The substrate layer includes a plurality of unit cells which are continuous, and the dielectric layer includes a plurality of nano-structures which are disposed with a predetermined distance therebetween. The single nano-structure is disposed on the unit cell, and a hologram image is formed when an incident light from a light source is reflected by the nano-structure so that a phase of the light is controlled.
