Techniques for analyzing driving simulations and determining simulation stability metrics are discussed herein. Various techniques may include receiving a driving simulation and determining a number of perturbed simulations based on the driving simulation. The perturbed simulations may include, for example, one or more perturbed object attributes, perturbed simulation failure conditions, and/or perturbed behaviors of the vehicle system on which the simulation is executed. The perturbed simulations may be executed, and the results may be analyzed to determine a stability score associated with the driving simulation. Stability scores for driving simulations may be determined and maintained based on different simulation data perturbations received based on perturbation models, and the stability scores may be used in various implementations to generate simulation batteries for regression testing and for analyzing and routing simulation failures.

Simulation stability analyses based on parameter perturbation

A fishing lure is molded of flexible plastic in the shape of an actual fish. The front or head region of the lure includes an internal brace or plate of metal. The rear or tail region of the lure has only the flexible plastic material. As the lure is towed under water by the fishing line, the massive and rigid head region swims straight onward, while the flexible and light-weight tail region waves back and forth in the water stream, imitating the propulsive tail motions of a living, swimming fish. This make the lure realistic. The caudal or tail fin includes a deflection plate along its lower edge which encourages swimming by setting up vortices in the water. Stabilizing fins or wings project horizontally from either side of the head region adjacent the brace, which flap and dampen any tendency toward pitching oscillations. The lure may be shaped and colored to resemble a particular species of fish. A hook may be molded into the brace, and project out from the plastic body.

Realistic swimming fish lure

A fishing lure has the shape of a squid. The lure comprises two sections: the rear body section which resembles the tapered rear part of a squid and the rounded front section or head which includes eyes and a fringed skirt resembling the squid's tentacles. The body and the head may be molded of rubber or plastic, and may be in the form of a hollow sheath. The rear and front parts are joined by a hinge which allows swiveling motion. The body and head are both radially symmetrical and each includes an internal weight. The body includes a central metal rod. The rod protrudes from the conical tip of the body and terminates in an eye loop where a fishing line is tied. The front end of the rod connects to the hinge, which may be simply two interhooked wire loops. The head has eye bulges and includes a second internal weight which is fixed directly to the hinge. A hook is mounted on the other side of the head weight. The hook is disposed within the tenacles. The rounded rear part of the head fits partially within a hollow on the forward end of the body; the hinge in hidden within.
