Abstract: An identification apparatus acquires a protein file in which a plurality of proteins including a plurality of amino acids are arranged. The identification apparatus identifies a plurality of primary structure candidates with any position included in the protein file as a starting position. The identification apparatus identifies one primary structure among the primary structure candidates based on a combination of a primary structure and each amino acid and a primary structure table, where the each amino acid is positioned at an end of the primary structure and the primary structure table associates a primary structure and a cooccurrence rate of a certain amino acid combination positioned at an end of the primary structure.

Abstract: When a player character applies a damage to an attack target character on the basis of an attack action of the player character, it is determined whether the attack is a direct attack or a specific kind of attack different from the direct attack and defined in advance. A panic reaction term of a panic reaction is determined in the case where it is determined that the attack is the specific kind of attack. In the panic reaction, the attack target character becomes a state where the attack target character cannot attack the player character and defend oneself from an attack from the player character. The panic reaction is executed until the panic reaction term elapses. A privilege is applied to the player character in the case where it is determined that the attack target character suffers the direct attack during execution of the panic reaction.
