Constrained constructive optimization (CCO) is a commonly used algorithm for vascular simulation, particularly well known for its adaptability toward vascular modeling across tissues. The present work demonstrates an implementation of CCO aimed to simulate a branching arteriolar microvasculature in healthy ...
The computational method of constrained constructive optimization was used to generate complex arterial model trees by optimization with respect to a target function. Changing the target function also changes the tree structure obtained. For a parameterized family of target functions a series of trees wa...

The last decade of phylogenetics has seen the development of many methods that leverage constraints plus dynamic programming (CDP). The goal of CDP is to produce a phylogeny that is optimal with respect to some objective function and that lies within a constrained version of tree space. To our...

In the seminal work [2], the authors considered the noiseless setting and proposed the following optimization problem to recover x*minx∈Rn∥x∥1,s.t.y⊙Ψx≥0,and∥x∥2=1,where “⊙” and “≥” denote the Hadamard product and element-wise inequality, respectively. [11] also considered...
This special variant of a multi-objective optimization problem considers the total number of required trucks as main objective dominating all other goals due to the high cost of labor. However, after fixing the overall number of trucks (and thus the number of required personal) secondary ...

The computational method of constrained constructive optimization (CCO) has been generalized in two important respects: (1) arterial model trees are now grown within a convex, three-dimensional piece of tissue and (2) terminal flow variability has been incorporated into the model to account for ...
