The present invention applies genetic algorithmic generation of test cases the simulation of VLSI logic circuit blocks. Background is reduced by introducing an intended mismatch with a target sequence in at least one of the probes. 0, the desorption of a gas mixture G-1 from a composition, the contacting of the gas mixture G-1 with a solvent mixture at least comprising 50% by weight of water based on the overall solvent mixture, the pH of the solvent mixture being in the range from 2. The dcap is inserted in the region having the most edges. For example, when the external apparatus is connected to the information processing apparatus, the setting in the information processing apparatus is automatically changed in correspondence with that in the external apparatus.
