Projection-onto-constraint sets is an efficient algorithm for constructing synthetic discriminant functions to be employed in pattern-recognition systems. The algorithm is implemented by a digital procedure based on a simulated joint-transform correlator.

A novel adaptation of impact-based search strategies for constraint-based resource scheduling is presented. Search based on impacts applies a general purpose search strategy originally from Linear Integer Programming and recently adapted to Constraint Programming. To my knowledge it is shown for the first time that this strategy is properly applicable to constraint-based scheduling and performs...

Abstract This paper presents a joint–coordinate adjoint method for optimal control of multi-rigid-body systems. Initially formulated as set differential-algebraic equations, the system is brought into minimal form by projecting original expressions joint’s motion and constraint force subspaces. Consequently, cumbersome partial derivatives corresponding to joint-space equations are avoided, appr...

“Heuristic synergy” refers to improvements in search performance when the decisions made by two or more heuristics are combined. This paper considers combinations based on products and quotients, and then a newer form of combination based on weighted sums of ratings from a set of base heuristics, some of which result in definite improvements in performance. Then, using recent results from an fa...

the realization optimality theory is a recent development in the original optimality theory which is proposed to deal with morphological issues especially the inflectional ones. its main idea is to consider the morphological realization rules as ranked violable language-specific constraints that control the realization processes and provide phonological information of grammatical morphemes. thi...

Recognizing structure of human body is important for modeling human motion. Human body is usually represented as an articulate model, which consists of the rigid parts and the joint points between them. The structure of the human body is specified by the joint points. In this paper we propose a novel method for estimating the location of joint points from successive volume data. Our joint point...

A key feature of constraint programming is the ability to design specific search strategies to solve problems. On the contrary, integer programming solvers have used efficient general-purpose strategies since their earliest implementations. We present a new general purpose search strategy for constraint programming inspired from integer programming techniques and based on the concept of the imp...

this study set out to investigate the distribution of the syntactic properties associatedwith the prodrop parameter by persian-speaking l2 learners of english in an attemptto examine the (un)attainability of native-like knowledge and (in)accessibility of ugin adult sla. to do so, 92 participants were assigned into different levels of l2knowledge based on their performances on the oxford placeme...

The influences of geometric constraint errors on the mobility of a 3-DOF translational parallel manipulator (TPM) are discussed in this paper. It is demonstrated based on screw theory that the mobility of the TPM may vanish if there exist manufacturing and installation errors violating the constraint conditions. To avoid such a zeromobility case, the original manipulator is converted into a non...

In this talk I shall explore the relationship between constraint-based mining and constraint programming. In particular, I shall show how the typical constraints used in pattern mining can be formulated for use in constraint programming environments. The resulting framework is surprisingly flexible and allows one to combine a wide range of mining constraints in different ways. The approach is i...
