A system and method for determining an optimal set of routes from an origin to one or more destinations. The system comprises a reverse geo-code database of closest intersections for one or more locations of a particular geographical region, a matrix generator, and a vehicle routing problem solver. The matrix generator creates a set of shortest routes among the possible routes between the origin location and the one or more destination locations. The shortest routes are determined by calculating a distance from a first location to a first nearest artery, a distance from a second location to a second nearest artery, and from the first nearest artery to the second nearest artery. The vehicle routing problem solver generates an optimal set of routes connecting the one or more locations by combining the one or more shortest routes.

The present invention provides computer implemented methodology that permits the safe landing and recovery of rotorcraft following engine failure. With this invention successful autorotations may be performed from well within the unsafe operating area of the height-velocity profile of a helicopter by employing the fast and robust real-time trajectory optimization algorithm that commands control motion through an intuitive pilot display, or directly in the case of autonomous rotorcraft. The algorithm generates optimal trajectories and control commands via the direct-collocation optimization method, solved using a nonlinear programming problem solver. The control inputs computed are collective pitch and aircraft pitch, which are easily tracked and manipulated by the pilot or converted to control actuator commands for automated operation during autorotation in the case of an autonomous rotorcraft. The formulation of the optimal control problem has been carefully tailored so the solutions resemble those of an expert pilot, accounting for the performance limitations of the rotorcraft and safety concerns.

A problem solver for generating an action sequence executed from an initial state to a goal state in a state space defined by a particular problem is disclosed, that comprises a cognitive distance learning unit learning a cognitive distance that represents a cost acted on the environment of the state space, the cost being spent in an action sequence executed from a first state in the state space to a second state that is different from the first state, and a next action deciding unit deciding a next action contained in the action sequence that has to be executed in a particular state to attain the goal state in the state space based on the cognitive distance learnt by the cognitive distance learning unit.< / PTEXT>

Internet web server based method / system for providing confidential, moderated, crowdsourced problem solving resources to solve various problems. A crowdsource database of various skilled individuals interested in acting as problem solvers and team facilitators is provided, along with a database of client proposed problems, divided into non-confidential and confidential problem statement sections, key skills needed, and other criteria. These criteria are used as an index to the crowdsource database, and potential matches found. An administrator uses a server provided dashboard GUI, and the non-confidential problem statements, to pick among the various proposed matches, determine interest, and form small facilitator moderated teams. After suitable NDA, the confidential problem statement is revealed, and the teams interact confidentially with the client through the server. Facilitator moderation, problem restatement, and other methods reduce burden on the client and improve solution quality. Client accepted solutions, optionally after team release of IP, result in team member payment.

The present invention provides systems and methods for guiding user development and documentation of thinking about an arbitrary problem according to exemplary approaches used by expert problem solvers.

The invention discloses a rapid microwave imaging method. In each iteration process of a DBIM algorithm, an inversion speed is improved by calling an efficient forward problem solver to calculate a forward problem. Meanwhile, in order to enable a whole inversion algorithm to stably carry out iterative inversion, a truncated singular value decomposition (TSVD) technology is adopted, and a large number of numerical tests are prevented from being used for determining regularization terms. In order to further reduce a calculated amount, in a cost function of an inversion algorithm, an incident field is used to replace a total field. Therefore, the method can achieve quick and stable inversion, and an inversion speed and quality of an image are ensured.

The invention discloses a content-based constraint-aware service combination method, including: selecting a candidate third-party service platform / service according to functional / non-functional characteristics, user preference and trust degree, and querying and obtaining content services; solving the combination problem The solver generates multiple solutions for the user based on different optimization objectives; when the user's constraints are too strict to cause an over-constrained problem, the over-constrained problem solver perceives the preference order of the user's constraints, generates the largest set of corrective constraint relaxation, and calls the combined problem solver Regenerate the plan; through the user constraint guidance mechanism, comprehensively consider the degree of satisfaction of the plan-user constraints, the representativeness of the plan and the diversity of the set of plans, and perceive user feedback, and repeatedly return the most suitable k plans for the user until the user is satisfied . The invention simultaneously solves the over-constraint problem caused by too strict user constraints and the problem of too many solutions caused by too loose user constraints.
