Direct Access for Answers to Conjunctive Queries with Aggregation [PDF]
Logical Methods in Computer ScienceWe study the fine-grained complexity of conjunctive queries with grouping and aggregation. For common aggregate functions (e.g., min, max, count, sum), such a query can be phrased as an ordinary conjunctive query over a database annotated with a suitable

Negative results in the theory of games with lexicographic utilities [PDF]
When players may have lexicographic utilities, there are: (i) extensive games having a non-empty set of equilibria but empty sets of sequentially rational, sequential and perfect equilibria (ii) normal form games having a non-empty set of equilibria but ...

Lagrangian Duality for Multiobjective Programming Problems in Lexicographic Order
, 2020 This paper deals with a constraint multiobjective programming problem and its dual problem in the lexicographic order. We establish some duality theorems and present several existence results of a Lagrange multiplier and a lexicographic saddle point ...

Lexicographic Preferences in Discrete Choice Experiments: Consequences on Individual-Specific Willingness to Pay Estimates [PDF]
In discrete choice experiments respondents are generally assumed to consider all of the attributes across each of the alternatives, and to choose their most preferred.

Where Utility Functions Do Not Exist - A Note on Lexicographic Orders [PDF]
There seems to be some amount of confusion in the finance text books regarding the conditions under which an individual’s preferences can be represented by a utility function.

Introduction [Defining collocation for lexicographic purposes]
, 2016 This volume deals with collocations from a lexicographic perspective by addressing, in detail, the boundaries between collocations and other word combinations, the possibility of adapting the definition of collocation to the objectives of specific ...

From Ordients to Optimization: Substitution Effects without Differentiability [PDF]
This paper introduces the concept of ordient for binary relations (preferences), a relative of the concept of gradients for functions (utilities). The lexicographic order, albeit not representable, has an ordient.

Gröbner Basis Cryptanalysis of Ciminion and Hydra
IACR Transactions on Symmetric CryptologyCiminion and Hydra are two recently introduced symmetric key Pseudo- Random Functions for Multi-Party Computation applications. For efficiency, both primitives utilize quadratic permutations at round level.

On Solving The Systems of Algebraic Equations Using Gröbner Bases
Труды Института системного программирования РАН, 2018 Described and proved the algorithm for finding some solution of algebraic equations over arbitrary field k for zero dimension ideals if Gröbner basis of this ideal over lexicographic order is given.
