NACO is covered in Scopus.
Numerical Algebra, Control and Optimization (NACO) is an international journal devoted to publishing peerrefereed high quality original papers on any nontrivial interplay between numerical linear algebra, control and optimization. These three areas are closely related and complementary. The developments of many fundamentally important theories and methods in optimization and control are based on numerical linear algebra. Efficient implementation of algorithms in optimization and control also provides new theoretical challenges in numerical linear algebra. Furthermore, optimization theory and methods are widely used in control theory, especially for solving practical control problems. On the other hand, control problems often initiate new theory, techniques and methods to be developed in optimization.
The main objective of NACO is to provide a single forum for and promote collaboration between researchers and practitioners in these areas. Significant practical and theoretical problems in one area can be addressed by the use of appropriate recent advanced theory techniques and methods from the other two areas leading to the discovery of new ideas and the development of novel methodologies in numerical algebra, control and optimization.
The journal adheres to the publication ethics and malpractice policies outlined by COPE.

Inspired by the results in [S. S. Dragomir and I. Gomm, Num. Alg. Cont. $\&$ Opt., 2 (2012), 271278], we give some new bounds for two mappings related to the HermiteHadamard inequality for convex functions of two variables, and apply them to special functions to get some results for the $p$logarithmic mean. We also apply the HermiteHadamard inequality to matrix functions in this paper.

In this paper, we propose an iterative method for calculating the
largest eigenvalue of nonhomogeneous nonnegative polynomials. This
method is a generalization of the method in [19]. We also
prove this method is convergent for irreducible nonhomogeneous
nonnegative polynomials.

Let $G$ be a simple graph with vertex set $V(G)$ and edge set
$E(G)$. An edgecoloring $\sigma$ of $G$ is called an adjacent
vertex distinguishing edgecoloring of $G$ if $F_{\sigma}(u)\not=
F_{\sigma}(v)$ for any $uv\in E(G)$, where $F_{\sigma}(u)$ denotes
the set of colors of edges incident with $u$. A totalcoloring
$\sigma$ of $G$ is called an adjacent vertex distinguishing
totalcoloring of $G$ if $S_{\sigma}(u)\not= S_{\sigma}(v)$ for any
$uv\in E(G)$, where $S_{\sigma}(u)$ denotes the set of colors of
edges incident with $u$ together with the color assigned to $u$. The
minimum number of colors required for an adjacent vertex
distinguishing edgecoloring (resp. an adjacent vertex
distinguishing totalcoloring) of $G$ is denoted by $\chi_a^{'}(G)$
(resp. $\chi^{''}_{a}(G)$). In this paper, we provide upper bounds
for these parameters of the Cartesian product $G$ □ $H$ of two
graphs $G$ and $H$. We also determine exact value of these
parameters for the Cartesian product of a bipartite graph and a
complete graph or a cycle, the Cartesian product of a complete
graph and a cycle, the Cartesian product of two trees and the
Cartesian product of regular graphs.

In this paper, by virtue of the epigraph technique, we construct a new kind of closednesstype constraint
qualification, which is the sufficient and necessary condition to guarantee the
strong duality between a cone constraint composite optimization problem
and its dual problem holds. Under this closednesstype constraint qualification condition, we obtain a formula of subdifferential for composite functions and study a cone constraint composite DC optimization problem in locally convex Hausdorff topological vector spaces.

Multifingered handarm robots play an important role in dynamic manipulation tasks. They can grasp and move various shaped objects. It is important to plan the motion of the arm and appropriately control the grasping forces for the multifingered handarm robots. In this paper, we perform the grasping force based manipulation of the multifingered handarm robot by using neural networks. The motion parameters are analyzed and planned with the constraint of the multiarms kinematics. The optimal grasping force problem is recast as the secondorder cone program. The semismooth Newton method with the FischerBurmeister function is then used to efficiently solve the secondorder cone program. The neural network manipulation system is obtained via the fitting of the data that are generated from the optimal manipulation simulations. The simulations of optimal grasping manipulation are performed to demonstrate the effectiveness of the proposed approach.

In this paper, we establish convexity of some functions
associated with symmetric cones, called SC trace functions.
As illustrated in the paper, these functions play a key role in
the development of penalty and barrier function methods for
symmetric cone programs. With trace function method we offer much
simpler proofs to these useful inequalities.

In this paper, we will consider the problem of partially sparse
signal recovery (PSSR), which is the signal
recovery from a certain number of linear measurements when its part is known to be sparse. We establish and characterize
partial $s$goodness for a sensing matrix in PSSR. We show that the partial $s$goodness condition is equivalent to the partial null space property (NSP), and is weaker than partial restricted isometry
property. Moreover, this provides a verifiable approach for partial NSP via partial $s$goodness constants. We also give
exact and stable partially $s$sparse recovery via the partial $l_1$norm minimization under mild assumptions.

A modified FletcherReevesType derivativefree method for symmetric nonlinear
equations

In this paper, we propose a descent derivativefree method for
solving symmetric nonlinear equations. The method is an extension of
the modified FletcherReeves (MFR) method proposed by Zhang, Zhou and Li [25] to symmetric
nonlinear equations. It can be applied to solve largescale
symmetric nonlinear equations due to lower storage requirement.
An attractive property of the method is that
the directions generated by the method
are descent for the residual function. By the use of some backtracking line search technique,
the generated sequence of function values is decreasing. Under
appropriate conditions, we show that
the proposed method is globally convergent. The preliminary numerical
results show that the method is practically effective.
