Abstract: Provided are an optimization method, an information processing device, and an information processing system capable of efficiently performing a ground state search of a constrained binary quadratic model. The information processing device performs the ground state search for the constrained binary quadratic model by substituting the ground state search for the binary quadratic model in which the interaction relationship between variables has a complete bipartite graph structure. Here, this information processing device divides the variable group corresponding to the vertex set divided into two in the complete bipartite graph into a group capable of updating the state in which the constraint is satisfied. Then, this information processing device can update the group of each variable group in parallel based on the information of the energy function and the variable, and execute the process of searching the ground state.

Abstract: Provided is an optimization method including executing a ground state search for an interaction model by a ground state search in a surrogate interaction model including D (D is a natural number of three or more) variable groups each having N continuous variables by using an information processing apparatus, the interaction model having a third-order or higher-order energy function including N (N is a natural number) continuous variables and discrete variables. The ground state search is executed based on simulated annealing. An interaction relation of the surrogate interaction model has a complete D-part graph structure. A coupling is set between i-th variable pairs in the respective variable groups of the surrogate interaction model. The information processing apparatus is operated to simultaneously update all variables of one variable group from among the D variable groups when performing a state transition in the surrogate interaction model.

Abstract: A suspension system for an engine includes an engine mount and an electronic control unit. The engine mount has spring characteristics that are switchable between first spring characteristics and second spring characteristics. The electronic control unit is configured to switch the spring characteristics of the engine mount to the first spring characteristics when the rotational speed of the engine is lower than a predetermined rotational speed, and torque of the engine is equal to or larger than a predetermined torque. The electronic control unit is configured to switch the spring characteristics of the engine mount to the second spring characteristics when the rotational speed of the engine is lower than the predetermined rotational speed, and the torque of the engine is smaller than the predetermined torque.
