The earlier AC algorithms are often considered too inefficient, and many of the later ones are difficult to implement, and so AC-3 is the one most often taught and used in very simple constraint solvers. The AC-3 algorithm is not to be confused with the similarly named A3C algorithm in machine learning. [1]
The most popular constraint propagation method is the AC-3 algorithm, which enforces arc consistency. Local search methods are incomplete satisfiability algorithms. They may find a solution of a problem, but they may fail even if the problem is satisfiable. They work by iteratively improving a complete assignment over the variables.
In the full AC model the complete Kirchhoff laws are used: this results in highly nonlinear and nonconvex constraints in the model. When the full AC model is used, UC actually incorporates the optimal power flow problem, which is already a nonconvex nonlinear problem.
The AC-3 algorithm improves over this algorithm by ignoring constraints that have not been modified since they were last analyzed. In particular, it works on a set of constraints that initially contains all constraints; at each step, it takes a constraint and enforces arc consistency; if this operation may have produced a violation of arc ...
Long Island police have arrested and charged a second suspect in connection to the mysterious, month-long disappearance of 14-year-old Emmarae Gervasi, who her father believes was a victim of sex ...

The Dallas Cowboys may not have to look far to find their next head coach.. Eight days after the team parted ways with head coach Mike McCarthy (and amid swirling rumors about Colorado Buffaloes ...
Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer ...
