  • Publication number: 20200393798
    Abstract: A method for controlling an optimization device, the method comprising: obtaining a value of a state variable included in an evaluation function obtained by converting a problem stored in a storage unit; and performing a search for a minimum value of the evaluation function by repeating a process of updating the value of the state variable by a Markov chain Monte Carlo method based on a transition probability distribution that is represented by a function by which it is possible to normalize to one a sum of probabilities of transition from a current state represented by a current value of the state variable to each of a plurality of different states, in which a transition probability becomes larger than in a Boltzmann distribution as a change in the value of the evaluation function due to a change in the value of the state variable is positively larger.

  • Patent number: 10867086
    Abstract: A streakline visualization apparatus sets a partial region including a discrete point at a first position on a first streakline in an analysis space as an analysis target region of the discrete point. Based on a velocity of fluid in the analysis target region indicated by fluid information, the apparatus calculates a second position indicating a destination of a particle on the discrete point at a second analysis time point. Next, based on information about a structure in the analysis target region indicated by structure information, the apparatus determines a region occupied by the structure in the analysis target region at the second analysis time point. Next, based on the first and second positions, the apparatus determines whether a second streakline has entered the occupied region. If the second streakline has not entered the occupied region, the apparatus displays the second streakline passing through the second position.

  • Patent number: 10799191
    Abstract: In a streakline visualization apparatus, a processing unit calculates, by using an expression including a correction value for correcting an error attributable to accelerated motion of a plurality of grid points represented by position information, time differential values of velocities of fluid on the plurality of grid points at each of the plurality of first time points. The processing unit calculates, based on the velocities and the time differential values of the velocities of the fluid on the plurality of grid points at each of the plurality of first time points, positions of a series of a plurality of particles sequentially outputted from a particle generation source as analysis time progresses at each of a plurality of second time points having a second time interval shorter than the first time interval. The processing unit generates display information about a streakline indicating the series of the plurality of particles.

  • Publication number: 20200005475
    Abstract: A visualization apparatus detects a change in the shape of a solid model of a human body part based on images obtained by capturing the solid model. Next, the visualization apparatus generates a three-dimensional model reproducing the shape of the human body part in virtual space based on three-dimensional model data representing the shape of the human body part in three dimensions. The visualization apparatus further transforms the shape of the three-dimensional model into a transformed three-dimensional model in accordance with the change in the shape of the solid model. Then, the visualization apparatus outputs images of the transformed three-dimensional model.
