Fast Converging Algorithm for Weighted Sum Rate Maximization in Multicell MISO Downlink
IEEE Signal Processing Letters, 2012 The problem of maximizing weighted sum rates in the downlink of a multicell environment is of considerable interest. Unfortunately, this problem is known to be NP-hard.

Sums of weighted averages of gcd-sum functions, II [PDF]
Rocky Mountain Journal of Mathematics, 2020 In this paper, we establish the following two identities involving the Gamma function and Bernoulli polynomials, namely $$ \sum_{k\leq x}\frac{1}{k^s} \sum_{j=1}^{k^s}\log \left(\frac{j}{k^s}\right) \sum_{\substack{d|k \\ d^{s}|j}}f* (d) \quad {\rm and } \quad \sum_{k\leq x}\frac{1}{k^s}\sum_{j=0}^{k^{s}-1} B_{m}\sum_{\substack{d|k \\ d^{s}|j}} f ...

Economic Theory, 2020 AbstractWhen choosing an alternative that has multiple attributes, it is common to form a weighted sum ranking. In this paper, we provide an axiomatic analysis of the weighted sum criterion using a general choice framework. We show that a preference order has aweakweighted sum representation if it satisfies three basic axioms: Monotonicity, Translation

A new method of decision making in multi-objective optimal placement and sizing of distributed generators in the smart grid [PDF]
Archives of Electrical Engineering, 2023 One of the most important aims of the sizing and allocation of distributed generators (DGs) in power systems is to achieve the highest feasible efficiency and performance by using the least number of DGs. Considering the use of two DGs in comparison to a

Sums of weighted averages of gcd-sum functions [PDF]
International Journal of Number Theory, 2018 Let [Formula: see text] be the greatest common divisor of the integers [Formula: see text] and [Formula: see text]. In this paper, we give several interesting asymptotic formulas for weighted averages of the [Formula: see text]-sum function [Formula: see text] and the function [Formula: see text] for any positive integers [Formula: see text] and ...

Better Sum Estimation via Weighted Sampling [PDF]
ACM Transactions on Algorithms, 2022 Given a large set U where each item a ∈ U has weight w ( a ), we want to estimate the total weight \(W=\sum _{a∈ U} w(a)\) to within factor of 1± ɛ with some ...

Arithmetic-progression-weighted subsequence sums [PDF]
Israel Journal of Mathematics, 2012 Let $G$ be an abelian group, let $S$ be a sequence of terms $s_1,s_2,...,s_{n}\in G$ not all contained in a coset of a proper subgroup of $G$, and let $W$ be a sequence of $n$ consecutive integers. Let $$W\odot S=\{w_1s_1+...+w_ns_n:\;w_i {a term of} W,\, w_i\neq w_j{for} i\neq j\},$$ which is a particular kind of weighted restricted sumset.
