Combinatorial Optimization for Artificial Intelligence Enabled Mobile Network Automation
2021
This chapter discusses combinatorial optimization techniques for enabling intelligent automation in mobile networks. A number of discrete optimization problems pertinent to mobile network automation can be solved effectively using artificial intelligence based combinatorial optimization approaches such as heuristics and metaheuristics. Relevant use-cases include both initial parameter assignment during network roll-out, and continuous optimization of configuration management parameters during network operation and maintenance. We discuss mobile network automation use-cases and motivation for using different heuristics and metaheuristics in designing network optimization algorithms. To this …
Heuristic algorithms for a storage location assignment problem in a chaotic warehouse
2014
The extensive application of emerging technologies is revolutionizing warehouse management. These technologies facilitate working with complex and powerful warehouse management models in which products do not have assigned fixed locations (random storage). Random storage allows the utilization of the available space to be optimized. In this context, and motivated by a real problem, this article presents a model that looks for the optimal allocation of goods in order to maximize the storage space availability within the restrictions of the warehouse. For the proposed model a construction method, a local search algorithm and different metaheuristics have been developed. The introduced algorit…
Il provvedimento di assegnazione della casa familiare su un immobile ipotecato: quando le ragioni creditorie prevalgono su quelle della famiglia
2018
L'articolo, partendo dall'analisi di una sentenza del Tribunale di Bari, si occupa del provvedimento di assegnazione della casa familiare e della relativa opponibilità al creditore ipotecario che abbia acquistato il suo diritto in base ad atto iscritto anteriormente alla emissione o trascrizione del provvedimento stesso The article, starting from the analysis of a sentence of the Court of Bari, deals with the provision of assignment of the family home and its enforceability to the mortgage lender who has acquired his right on the basis of an act written before the issuance or transcription of the provision same
Multidimensional scaling and stock location assignment in a warehouse: an application
1999
By means of an application, in the present paper, the suitability of a multivariate statistical methodology, as multidimensional scaling (MDS), to solve an optimization problem is shown. In particular, considering the stock location assignment problem in the warehouse of a supermarket chain, the solution gained by applying MDS to a set of seven variables is compared with the one obtainable by considering the usual techniques applied in this context. A wide discussion of results is reported.
Effects of environment and genotype on dispersal differ across departure, transfer and settlement in a butterfly metapopulation
2022
Active dispersal is driven by extrinsic and intrinsic factors at the three stages of departure, transfer and settlement. Most empirical studies capture only one stage of this complex process, and knowledge of how much can be generalized from one stage to another remains unknown. Here we use genetic assignment tests to reconstruct dispersal across 5 years and 232 habitat patches of a Glanville fritillary butterfly ( Melitaea cinxia ) metapopulation. We link individual dispersal events to weather, landscape structure, size and quality of habitat patches, and individual genotype to identify the factors that influence the three stages of dispersal and post-settlement survival. We found that ne…
Il ruolo dell'informazione contestuale e delle componenti sillabico-accentuali nella decodifica del testo scritto: un confronto tra dislessici evolut…
2010
L'esperimento qui presentato si propone di valutare l'importanza che assume, per un dislessico evolutivo rispetto ad un normolettore, la presenza di indizi che suggeriscano il significato del testo scritto (informazioni contestuali), nonché l'influenza di determinate caratteristiche sillabico-accentuali nelle prestazioni di lettura. Lo studio è stato condotto attraverso la somministrazione di frasi in ognuna delle quali è stata inserita una parola target secondo criteri relativi alla posizione (dislocazione a sinistra e dislocazione a destra) al fine di valutare l'influenza esercitata dall'informazione contestuale durante la decifrazione del testo. Le parole selezionate sono state accuratam…
A note on rank 2 diagonals
2020
<p>We solve two questions regarding spaces with a (G<sub>δ</sub>)-diagonal of rank 2. One is a question of Basile, Bella and Ridderbos about weakly Lindelöf spaces with a G<sub>δ</sub>-diagonal of rank 2 and the other is a question of Arhangel’skii and Bella asking whether every space with a diagonal of rank 2 and cellularity continuum has cardinality at most continuum.</p>
An Exact Algorithm for the Quadratic Assignment Problem on a Tree
1989
The Tree QAP is a special case of the Quadratic Assignment Problem (QAP) where the nonzero flows form a tree. No condition is required for the distance matrix. This problem is NP-complete and is also a generalization of the Traveling Salesman Problem. In this paper, we present a branch-and-bound algorithm for the exact solution of the Tree QAP based on an integer programming formulation of the problem. The bounds are computed using a Lagrangian relaxation of this formulation. To solve the relaxed problem, we present a Dynamic Programming algorithm which is polynomially bounded. The obtained lower bound is very sharp and equals the optimum in many cases. This fact allows us to employ a redu…
Frequency Assignment and Multicoloring Powers of Square and Triangular Meshes
2005
The static frequency assignment problem on cellular networks can be abstracted as a multicoloring problem on a weighted graph, where each vertex of the graph is a base station in the network, and the weight associated with each vertex represents the number of calls to be served at the vertex. The edges of the graph model interference constraints for frequencies assigned to neighboring stations. In this paper, we first propose an algorithm to multicolor any weighted planar graph with at most $\frac{11}{4}W$ colors, where W denotes the weighted clique number. Next, we present a polynomial time approximation algorithm which garantees at most 2W colors for multicoloring a power square mesh. Fur…
L'attribution des classes aux enseignants : le cas des écoles primaires
2007
Assigning teachers to classrooms: The case of French primary schools - This paper reports a study which focused on teachers'assignment in French elementary school whose headmasters have no decision-making powers. Using both in-depth interviews with 18 headmasters and data about teachers and classrooms within their schools, the analysis shows that the potential for problems is significant as far as teachers are sorted into classrooms based on their preference first. When those individual preferences compete, a few basic rules apply and some arrangements should be found amongst members of the staff. Actually, this study reveals that bargaining, or at times yielding to teachers'preferences abo…
