为解决机器人在路径规划中路径过长与后期寻优停滞的问题，提出了一种学习型多策略改进鲸鱼优化算法(reinforcement learning multi-strategy improvement whale optimization algorithm, RLMIWOA),并在欧式距离的基础上引入了障碍物信息与拐点信息，构建了路径规划适应度函数。首先，引入自适应帐篷映射初始化，使得初始化种群更加均匀；其次，引入了非线性收敛策略平衡算法的开发和探索阶段；然后，通过采用非线性加权因子对最优个体进行扰动，避免了其他个体对最优个体的“盲从”;最后，通过采用强化学习结合ε-精英逐维反向学习策略和动态局部最优逃生策略，提高了算法的收敛效率和跳出局部最优的能力。实验结果表明：RLMIWOA算法可以高效地找到最优路径，在路径搜索方面具有显著的优势。

Based on the newly constructed state|l,r>>[fan et al.,***.16(1999)706],where l is the angular mometum quantum number and r denotes the electron's orbit radius in a uniform magnetic field,we propose a new angular momentum-phase coherent state by introducing a new operator A.A and A^(†)are annihilation and creation operator in the|l,r>>space,*** coherent state is A's eigenket and possesses non-orthonormal and overcomplete properties,it is constructed on the certain superposition of zero-angular momentum states along the radius direction.

The strained cyclopropane and/or cyclobutane subunits occurred in many complex natural products including terpenoids, steroids and alkaloids. Natural products with cyclopropane and/or cyclobutane motifs not only furnished fascinating structures, but also exhibited versatile biological activities, such as cytotoxic, anti-HIM antimicrobial, antiviral, and immunosuppressive effects. This review covered a large array of structurally unique natural products with strained cyclopropane and/or cyclobutane motifs and summarized their structural features, distributions, biological activities, as well as biogenetic considerations.

Based on the technique of integration within an ordered product of operators, we derive new bosonicoperators' ordering identities by using entangled state representation and the properties of two-variable Hermite poly-nomials H and vice versa. In doing so, some concise normally (antinormally) ordering operator identities, such asa+man =:Hm,n(a+,a):, ana+m = (-i)m+n:Hm,n(ia+,ia): are obtained.

A couple of two-dimensional linear and fully nonlinear numerical models for compressible atmosphere are used to numerically study the propagation of the gravity wave packet into a mean wind shear. For a linear propagation wave packet, the critical level interactions are in good agreement with the linear critical level theory. The dynamically and convectively unstable regions are formed due to the critical level interaction of a finite-amplitude wave packet, but they would not break. The free exchange of potential energy with kinetic energy in the background atmosphere at rest ceases after entering the mean wind shear. However, it still goes on in the nonlinear propagation. It is shown that the nonlinear effects modify the mean flow markedly, reduce the momentum and energy propagation velocity and drop the elevation of the critical level. The gravity wave packet becomes unstable and breaks down into smaller scales in some regions. It expends much more kinetic energy than potential energy in the early phase of the breakdown. This means that the wave breakdown sets up due to the action of the shear instability rather than a convective one.

A type of special two-mode squeezed coherent state is constructed which is a characteristic of squeezing and displacing related. The new states take simpler and neater form than the usual two-mode squeezed coherent states, and also possess a completeness relation. It is expected that experimentalists woking on quantum optics should fabricate such a type of squeezed coherent optical field.

The explicit common eigenvectors for complex scalar fields φ (x) and φ+ (x) are derived . They span an orthonormal and complete space. Based on this, the charge conjugate unitary operator and the operator which generates Bogolyubov pseudo-particles transformation can be neatly derived. It is emphasized that | ξ> is different from the direct product of two independent eigenvectors respectively belonging to two real scalar fields, and | ξ > is named the correlated eigenstates of φ( x) and φ^+ (x).
